**An isosceles triangle** therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg).

## What do 2 angles of a triangle equal?

A triangle’s angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle.

## Is a triangle with two equal angles always isosceles?

If a triangle has two angles equal to each other, the sides which subtend the equal angles will also be equal to one another. Hence, by definition, such a triangle will be isosceles.

## Can a right angle triangle have two equal sides?

Yes, a right triangle can have two equal sides. The longest side is called the hypotenuse and the other two sides may or may not be equal to each other. A right triangle that has two equal sides is called an isosceles right triangle.

## What is a right angle triangle called?

A right triangle (American English) or right-angled triangle (British), or more formally an orthogonal triangle (Ancient Greek: ὀρθόςγωνία, lit. The side opposite to the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (or catheti, singular: cathetus).

## What does a right triangle equal to?

Right triangles are triangles in which one of the interior angles is 90 degrees, a right angle. Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary).

## Can a triangle have 3 right angles?

In Spherical Geometry, a triangle can have three right angles!

## How many right angles does a right triangle have?

A right triangle has only one right angle.

## Can a right triangle be isosceles?

Yes, a Right angle triangle can be an isosceles and scalene triangle but it can never be an equilateral triangle. An Isosceles triangle is a triangle in which at least two sides are equal. Since the two legs of the triangle are equal, which makes the corresponding angles equal to each other.

## What is the measure of the two equal angles of a right isosceles triangle?

ANSWER: Sum of all angles in a triangle in always 180 degree. ✏So, first is 90 degree as it is right angled triangle. Since the measure of equal angles is 45 degree.

## What’s a triangle with two equal sides called?

Isosceles. An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle.

## What is formula for right angle triangle?

The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2, is used to find the length of any side of a right triangle.

## What is right angle shape?

A right angle is an angle of 90°. When two rays intersect and form a 90˚ angle or are perpendicular to each other at the intersection, they are said to form a right angle. They are in the shape of the letter “L”.

## What are the different types of right triangles?

There are three types of special right triangles, 30-60-90 triangles, 45-45-90 triangles, and Pythagorean triple triangles.
