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.
In a convex quadrilateral, all interior angles are less than 180Â° and the two diagonals both lie inside the quadrilateral. 1  Irregular quadrilateral (British English) or trapezium (North American English): no sides are parallel. 2  Trapezium (UK) or trapezoid (US): at least one pair of opposite sides are parallel. Trapezia (UK) and trapezoids (US) include parallelograms. Isosceles trapezium (UK) or isosceles trapezoid (US): one pair of opposite sides are parallel and the base angles are equal in measure. Alternative definitions are a quadrilateral with an axis of symmetry bisecting one pair of opposite sides, or a trapezoid with diagonals of equal length. Parallelogram: a
