## What is it called when opposite angles are equal?

Opposite angles, angles that are opposite each other when two lines cross, are also known as vertical angles because the two angles share the same corner. Opposite angles are also congruent angles, meaning they are equal or have the same measurement.

**WHAT IS sides opposite to equal angles?**

Sides opposite to equal angles are always equal. Was this answer helpful?

**What is the rule for opposite angles?**

When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex.

### What are opposite sides in geometry?

In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles.

**What are opposite sides?**

The opposite side or part of something is the side or part that is furthest away from you.

**Does a triangle have opposite sides?**

In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle.

#### What is opposite angle example?

The opposite angles in a quadrilateral are those angles that are located diagonally opposite to each other. In other words, they are the angles that are connected through diagonals. For example, in the following parallelogram ABCD, ∠A and ∠C are called opposite angles. Similarly, ∠B and ∠D are opposite angles.

**What does opposite mean in geometry?**

**What are opposite angles?**

Opposite Angles are angles directly opposite to each other when two lines intersect in a plane. Opposite angles are also called Vertical Angles.

## Are all opposite angles equal?

Opposite angles are always equal. Two adjacent angles are always located next to each other. We have understood the concept of opposite angles with respect to intersecting lines. Now, let us understand the other concept of opposite angles with reference to a parallelogram and a cyclic quadrilateral.

**How to prove that sides opposite to equal angles are equal?**

Given :- A triangle ABC where ∠B = ∠C To Prove :- AB = AC Construction:- Draw a bisector of ∠A intersecting BC at D. Proof:- In △BAD and △CAD ∠ B = ∠ C ∠BAD = ∠CAD AD = AD △BAD ≅ △CAD Thus, AB = AC Hence, sides opposite to equal angles are equal. Hence proved

**How do you find the opposite angles of a triangle?**

In this case, ∠ D A C is the opposite angle to the side B C ― and ∠ D B C is also opposite angle to the side A C ―. The two angles are equals due to the congruency. Therefore, if two sides of a triangle are equal, then the angles opposite to them are also equal.

These are called opposite angles, vertical angles or vertically opposite angles. These angles are equal in measure. However, in geometry, the term ‘opposite angles’ is also used in quadrilaterals. These opposite angles are the angles that are diagonally opposite to each other.

### How many pairs of opposite angles in a kite are equal?

Only one pair of opposite angles in a kite are equal in measure. In a kite, there are two pairs of opposite angles. In these, there is one set of opposite angles that lies between the sides that are of different lengths. This pair of opposite angles is equal.
