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.

  1. An isosceles trapezoid has all the properties of a trapezoid.
  2. The legs of an isosceles trapezoid are congruent. This is the definition of an isosceles trapezoid.
  3. The base angles of an isosceles trapezoid are congruent. (see proof below)
  4. The diagonals of an isosceles trapezoid are congruent. (see proof below)
  • Isosceles trapezoid diagonals
  • Isosceles trapezoid angles
