# Isosceles Trapezoid

By the end of this lesson, you will be able to

• define isosceles trapeziod or trapeziem.
• relate isosceles trapeziod to trapeziod.
• describe diagonals of isosceles trapeziod
• draw examples of isosceles trapeziod.

## What is Isosceles Trapezoid

The trapeziod or trapeziem in which a pair of opposite sides is equal in length is called isosceles trapeziod or trapeziem.

Isosceles trapeziod is a particular type of trapeziod whose two sides are equal.

An isosceles trapezoid

Another way..., n isosceles trapezoid is a trapezoid in which the diagonals are of equal length.

Two opposite parallel sides are called the bases of an isosceles trapezoid.

There are two parallel sides; and other two sides are called legs of an isosceles trapezoid.

Two legs are equal in length.

The base angles are of equal measure. Two parallel sides are called the base of the trapeziod. Another two sides other than parallel sides are called legs of the trapeziod. Two legs of an isosceles trapeziod are of equal in length.

Again, the two legs produced angles to base or parallel sides are called base angle of isosceles trapeziod. For an isosceles trapeziod, two base angles are equal in measure.
