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.
A Trapezoid is a 4-sided polygon (Quadrilateral) which has at least one pair of parallel sides. The sides of a Trapezoid that are parallel are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides. The perpendicular distance from one base to the other is called the altitude of a trapezoid.
