If a quadrilateral is an isosceles trapezoid, then it must satisfy certain conditions:

1. Definition: An isosceles trapezoid is a type of trapezoid where the non-parallel sides are congruent (equal in length). The parallel sides of an isosceles trapezoid are called the bases, and the non-parallel sides are known as the legs.

2. Two congruent sides: In an isosceles trapezoid, the legs (the non-parallel sides) are equal in length. This creates two congruent triangles within the trapezoid.

3. Base angles: The angles formed by one leg with each of the bases are equal. In other words, the two angles opposite the legs (also known as the base angles) are congruent.

4. Diagonals: The diagonals of an isosceles trapezoid are equal in length. The diagonals connect the non-adjacent vertices of the trapezoid (i.e., the endpoints of the bases).

5. Midline: The midpoint of the trapezoid’s bases forms a line segment called the midline. The midline is parallel to the trapezoid’s bases and is equal in length to the average of the lengths of the bases.

These properties are specific to an isosceles trapezoid and provide unique characteristics that distinguish it from other types of quadrilaterals. Understanding these properties and their relationships can help in solving mathematical problems and proofs related to isosceles trapezoids.
