Quadrilaterals which have one pair of parallel sides are called trapezoids. Sides that are parallel are called bases of a trapezoid, and ones that are not parallel are called legs. Trapezoids whose legs are of equal length are called isosceles trapezoids. Diagonals of a isosceles trapezoids are congruent.
Definition of a Trapezoid. As a quadrilateral, the trapezoid is a four sided shape. The first unique property about the trapezoid is that it has only one pair of parallel sides (AB and CD as shown below). The trapezoid is also sometimes referred to as the trapezium, but they are the same shapes.
