Lesson 6-5 Trapezoids and Kites

Trapezoid Definition: A quadrilateral with exactly one pair of parallel sides. The parallel sides are called bases and the non-parallel sides are called legs. Trapezoid Base Leg An Isosceles trapezoid is a trapezoid with congruent legs. Isosceles trapezoid

Properties of Isosceles Trapezoid 1. Both pairs of base angles of an isosceles trapezoid are congruent. 2. The diagonals of an isosceles trapezoid are congruent. B A Base Angles D C

Median of a Trapezoid The median of a trapezoid is the segment that joins the midpoints of the legs. The median of a trapezoid is parallel to the bases, and its measure is one-half the sum of the measures of the bases. Median
