Trapezoids and Kites 1/16/13 Mrs. B Slide 2 Objectives: Use properties of trapezoids. Use properties of kites. Slide 3 Using properties of trapezoids A trapezoid is a quadrilateral with exactly one pair of parallel sides called bases. A trapezoid has two pairs of base angles. Ex. D and C And A and B. The nonparallel sides are the legs of the trapezoid. Slide 4 Using properties of trapezoids If the legs of a trapezoid are congruent, then the trapezoid is an isosceles trapezoid. Slide 5 Isosceles Trapezoid If a trapezoid is isosceles, then each pair of base angles is congruent. A B, C D Slide 6 Isosceles Trapezoid If a trapezoid is isosceles, then adjacent angles (not bases) are supplementary.
