Interview about love triangles and the geometry of love.

How they appear and how they live in them.

The time of falling in love brings not only romance, but sometimes big problems- if an unexpected feeling arose in the family of the partners, but not at all towards each other.

Adult game

- This phenomenon is probably an eternal problem for married couples?

In almost all multi-page love novels of past centuries, and even the present one, one can find a description of mental turmoil due to life in love triangles. When she loves one, but lives with another, and he loves her, but dates another.

I don’t understand when they say that this has never happened before. And it cannot be said that there are more love triangles now. Love triangles are a magnificent and most interesting adult game. Better than computer games, stronger than drugs.

- How do they turn out? love triangles?

First of all, it is a form of complex relationship, a sign of a crisis between people who live together. The presence of a third, oddly enough, makes these relationships more stable. After all, a triangle is the most stable figure in geometry. And in psychotherapy there is a stool principle: a stool will never stand on two legs; for stability, at least a third is needed.

Therefore, during a crisis in a family, each of its participants at a certain moment may begin to look for that person with whom it will be a little better, more comfortable. And it’s not about sex at all, but about human relationships.

- What does a relationship crisis look like?

For example, there is a couple in which something begins to happen that makes the life of one unbearable. The reason is a chronic lack of emotions, attention, affection, recognition, respect, and so on. At one point, another person appears who can fill this deficit.

I remember there was a curious incident. The man lived in marriage for a very long time. They had children. And suddenly, unexpectedly for himself, as he says, he began dating another woman. At an appointment with a psychotherapist, the man admitted that he did not understand why he was attracted to her. “She is not as good as my wife, she is not as beautiful, not as successful. Actually worse than my wife. But I think about her every day.”

To the question “What do you get from her,” the client answered: “Every time I hear that I am good and delightful.” When there is no openness, recognition, or spiritual closeness in a family, then any person begins to look for it on the side.

- But what about the accidents that are also described in novels?

I don't really believe in chance. When people get married or even just start living together, they know what they're signing up for. A man himself chooses the woman with whom he is going to live. Here he meets someone else on the side and it seems like some decision needs to be made, but the love triangle allows you to leave everything as it is. A man understands how “convenient” it is to have both a mistress and a wife. And a woman sees how comfortable it is when there is a lover and a husband.

And for recent years two, I noticed that an equal number of mistresses who were in relationships with married men and wives whose husbands were cheating began to come to the reception. At the same time, there are many times fewer men with this topic in consultations. This says that it is always more convenient for a man to have, on the one hand, official difficult relationships with his wife, on the other - light and pleasant with his mistress. But this situation lasts for the time being.

The price of comfort

- How long can a love triangle last? After all, untruth always becomes obvious.

In my memory, the longest lasted 15 years - for so many years the mistress waited for a man. When you enter into such a relationship, you must always be aware of the price you have to pay, and sometimes the price is too high. There is a stereotype - every mistress wants to become a wife.

More often there is a situation when a woman cannot wait for a man for a long time, and a wife cannot tolerate her husband’s infidelity for a long time. This causes a lot of tears, irritation, worries, resentment and guilt. An exception to the rule is a wife and girlfriend’s mistress who know about each other, discuss their husband and everyone is comfortable and happy.

- How to exist in such a situation?

Everyone in the love triangle has their own role. A man, complaining to his mistress about his wife, looks for a savior in her. It's always nice when you are saved from a bad wife. The wife acts as the pursuer. She always says that her husband is bad and persecutes her mistress, for some reason accusing her of destroying the family. Moreover, then the roles change, and the deceived wife becomes a victim, upset that she is being deceived, and the husband finds himself in the role of a rescuer. Everyone plays, walks around the edge and waits. This kind of life is very exciting and becomes comfortable.

Play by the rules

The rules of life in a love triangle are simple. One must persecute the other, the other must be to blame. The first one should feel great pleasure from the fact that he suffers from remorse - demand attention to himself, break off relationships, then suffer that he did not leave, and so on.

At the same time, a man feels something like this: how can I cope with everyone? And he is a kind of defector between the two sides. And he likes it, because if the game weren’t so interesting, they wouldn’t play it. It adds experience and relieves tension in relationships. You can play endlessly, but the one who gives up, in the sense of making a decision first, wins.

I recommend asking questions to all three: how long are you willing to wait for changes in the couple, and what are you willing to do yourself in order to change something? Are you ready to get out of it if you are tired of it? How profitable is it for you to play?

Sometimes you have to give up, try to move away, let go, and then the triangle falls apart. After all, it exists as long as three people are involved in it.

From practice

- How often do love triangles end? Divorce or saving the family?

In a relationship in a love triangle, if a divorce does not take place in the first two years, there is a high probability that it will not happen. Women dating married man, they think: “When he gets divorced, he and I will have a strong, happy family.” Unfortunately, in 90% of cases this is not the case. Because the roles in a love triangle are clearly distributed, and for a man, a mistress will almost never become a wife.

The context of the relationship between lovers usually does not transfer into the relationship between husband and wife, even if they register, since this requires big changes in the relationship, and sometimes completely different relationships. There is a high probability that in this case the man may look for a mistress again.

By the way

The theme of love is full of myths and stereotypes. For example, around absolute polygamy and monogamy, which in fact do not exist. Because every species, including people, must develop and give birth to healthy offspring. Anthropologists, studying the nature of people, have come to the conclusion that men and women are equally polygamous and monogamous until they find the best partner with whom they can live their entire lives.

Let's start by defining what an angle is. Firstly, it is Secondly, it is formed by two rays, which are called the sides of the angle. Thirdly, the latter emerge from one point, which is called the vertex of the angle. Based on these characteristics, we can make a definition: angle - geometric figure, which consists of two rays (sides) emerging from one point (vertex).

They are classified by degree value, by location relative to each other and relative to the circle. Let's start with the types of angles according to their magnitude.

There are several varieties of them. Let's take a closer look at each type.

There are only four main types of angles - straight, obtuse, acute and straight angles.

Straight

It looks like this:

Its degree measure is always 90 o, in other words, a right angle is an angle of 90 degrees. Only such quadrilaterals as square and rectangle have them.

Blunt

It looks like this:

The degree measure is always more than 90 o, but less than 180 o. It can be found in quadrilaterals such as a rhombus, an arbitrary parallelogram, and in polygons.

Spicy

It looks like this:

The degree measure of an acute angle is always less than 90°. It is found in all quadrilaterals except the square and any parallelogram.

Expanded

The unfolded angle looks like this:

It does not occur in polygons, but is no less important than all the others. A straight angle is a geometric figure whose degree measure is always 180º. You can build on it by drawing one or more rays from its top in any direction.

There are several other minor types of angles. They are not studied in schools, but it is necessary to at least know about their existence. There are only five secondary types of angles:

1. Zero

It looks like this:

The name of the angle itself already indicates its size. Its internal area is 0°, and the sides lie on top of each other as shown in the figure.

2. Oblique

An oblique angle can be a straight angle, an obtuse angle, an acute angle, or a straight angle. Its main condition is that it should not be equal to 0 o, 90 o, 180 o, 270 o.

3. Convex

Convex angles are zero, straight, obtuse, acute and straight angles. As you already understood, the degree measure of a convex angle is from 0° to 180°.

4. Non-convex

Angles with degree measures from 181° to 359° inclusive are non-convex.

5. Full

A complete angle is 360 degrees.

These are all types of angles according to their magnitude. Now let's look at their types according to their location on the plane relative to each other.

1. Additional

That's two acute angles, forming one straight line, i.e. their sum is 90 o.

2. Adjacent

Adjacent angles are formed if a ray is passed through the unfolded angle, or rather through its vertex, in any direction. Their sum is 180 o.

3. Vertical

Vertical angles are formed when two straight lines intersect. Their degree measures are equal.

Now let's move on to the types of angles located relative to the circle. There are only two of them: central and inscribed.

1. Central

A central angle is an angle with its vertex at the center of the circle. Its degree measure is equal to the degree measure of the smaller arc subtended by the sides.

2. Inscribed

An inscribed angle is an angle whose vertex lies on a circle and whose sides intersect it. Its degree measure is equal to half the arc on which it rests.

That's it for the angles. Now you know that in addition to the most famous ones - acute, obtuse, straight and deployed - there are many other types of them in geometry.

Each angle, depending on its size, has its own name:

Angle type Size in degrees Example
Spicy Less than 90°
Straight Equal to 90°.

In a drawing, a right angle is usually denoted by a symbol drawn from one side of the angle to the other.

Blunt More than 90° but less than 180°
Expanded Equal to 180°

A straight angle is equal to the sum of two right angles, and a right angle is half of a straight angle.

Convex More than 180° but less than 360°
Full Equal to 360°

The two angles are called adjacent, if they have one side in common, and the other two sides form a straight line:

Angles MOP And PON adjacent, since the beam OP- the common side, and the other two sides - OM And ON make up a straight line.

The common side of adjacent angles is called oblique to straight, on which the other two sides lie, only in the case when adjacent angles are not equal to each other. If adjacent angles are equal, then their common side will be perpendicular.

The sum of adjacent angles is 180°.

The two angles are called vertical, if the sides of one angle complement the sides of the other angle to straight lines:

Angles 1 and 3, as well as angles 2 and 4, are vertical.

Vertical angles are equal.

Let's prove that vertical angles are equal:

The sum of ∠1 and ∠2 is a straight angle. And the sum of ∠3 and ∠2 is a straight angle. So these two amounts are equal:

∠1 + ∠2 = ∠3 + ∠2.

In this equality, there is an identical term on the left and right - ∠2. Equality will not be violated if this term on the left and right is omitted. Then we get it.
