Isosceles Trapezoid
What is an Isosceles Trapezoid?
An Isosceles Trapezoid is a trapezoid with
congruent legs. Isosceles Trapezoids are special trapezoid with
special and unique properties. Below is an example of an
Isosceles Trapezoid. The Isosceles Trapezoid angles are
equal as shown. This is a math help section for isosceles
trapezoids. We will discuss properties of an Isosceles
Trapezoid in detail below.
Properties of an isosceles trapezoid
The definition and properties of isosceles
trapezoids below shows how to construct an isosceles
trapezoid.

An isosceles trapezoid has all the properties of a
trapezoid.

The legs of an isosceles trapezoid are congruent.
This is the definition of an isosceles trapezoid.

The base angles of an isosceles trapezoid are
congruent. (see proof below)

The diagonals of an isosceles trapezoid are
congruent. (see proof below)
