## What defines an isosceles triangle?

: a triangle in which two sides have the same length.

## What are 3 characteristics of isosceles triangles?

An isosceles triangle is a triangle that: Has two congruent sides. Has congruent base angles. Has an altitude which: (1) meets the base at a right angle, (2) bisects the apex angle, and (3) splits the original isosceles triangle into two congruent halves.

## How do you identify an isosceles triangle?

Identifying isosceles triangles

An isosceles triangle has two equal sides (or three, technically) and two equal angles (or three, technically). The equal sides are called legs, and the third side is the base. The two angles touching the base (which are congruent, or equal) are called base angles.

## Can a right triangle be isosceles?

In a right triangle, one of the angles is a right angle? an angle of 90 degrees. A right triangle may be isosceles or scalene.

## How do you find the isosceles triangle with two equal sides?

So you're going to take the square root of B squared and B is the side the base divided. By four andMoreSo you're going to take the square root of B squared and B is the side the base divided. By four and then we're going to add the height squared well the height is going to be this internal height.

## Do isosceles triangles add up to 180?

The sum of three angles of an isosceles triangle is always 180°, which means we can find out the third angle of a triangle if the two angles of an isosceles triangle are known.

## How do you find the third side of a triangle if two sides are known?

You can use the Pythagorean Theorem to find the length of the hypotenuse of a right triangle if you know the length of the triangle's other two sides, called the legs. Put another way, if you know the lengths of a and b, you can find c.

## What is a triangle with no sides the same?

Scalene. A scalene triangle has three different angles and none of its sides are equal in length.
