es mZABE mZEAB = 32 Given m2BEA=90 mZBEA+mZEAB+mZABE= = 180 90 +32+x=180 122+x=180 In kite ABCD, mZEAB = 32 and m/BCE=62. Property that diagonals of a kite are perpendicular A ABE is a right triangle Substitute Combine like terms x = 58 Subtract 122 on both sides mZABE = 58 Your Turn 1. According to the four kite theorems, label the kites appropriately. 1 Kite Theorems If a quadrilateral is a kite, then If a quadrilateral is a kite, then If a quadrilateral is a kite, then If a quadrilateral is a kite, then 2. In kite WYZ, MYXV = 42 and mDYZV = 30. Find mDXYV W
