1. LESSON 6.5 TRAPEZOIDS AND KITES OBJECTIVE: Verify and use properties of trapezoids and kites

2. Definitions base leg The base angles of a trapezoid are 2 angles that share a base of the trapezoid. base angles

3. The base angles of an isosceles trapezoid are Trapezoid Theorems congruent. Theorem 6.15

4. D C A B The diagonals of an isosceles trapezoid are Theorem 6.16 congruent. AC  BD

5. The diagonals of a kite are KITE THEOREM perpendicular. A D C B AC  BD Theorem 6.17

6. EXAMPLE #1WXYZ is an isosceles trapezoid. Find the other missing angles. m  X + m  W = 180 Bases are in a trapezoid. Angles that share a leg are. 156 + m  W = 180 m  W = 24  parallel SSI
