Trapezoids and Kites

Trapezoids and Kites A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are of trapezoid are called bases. The nonparallel sides are called legs. The two angles that share a base of a trapezoid are called base angles. A trapezoid has two pairs of base angles.

Trapezoids and Kites An isosceles trapezoid is a trapezoid with legs that are congruent. ABCD below is an isosceles trapezoid. The angles of an isosceles trapezoid have some unique properties.
