# Isosceles Trapezoid Conjecture

### Explanation:

A **trapezoid** is a quadrilateral with exactly one pair of parallel sides. In a trapezoid the parallel sides are called **bases**. A pair of angles that share a base as a common side are called a pair of **base angles**.
A trapezoid with the two non-parallel sides the same length is called an **isosceles trapezoid**. This conjecture tells us that the base angles of an isosceles trapezoid are equal in measure.

### The precise statement of the conjecture is:

**Conjecture (***Isosceles Trapezoid * ):
The base angles of an isosceles trapezoid are equal in measure.
