![]() mBCD + mCBF + mCDF = 180°Įxample 2A Continued mBCD + mCBF + mCDF = 180° Substitute mCDF for mCBF. ∆base s CBF CDF mCBF = mCDF Def. 4 Check It Out! Example 1 Continued Look BackĮxample 2A: Using Properties of Kites In kite ABCD, mDAB = 54°, and mCDF = 52°. The perimeter of the kite is approximately 2(54) + 2 (41) = 190. To estimate the perimeter, change the side lengths into decimals and round. In order to have enough, Daryl must buy 3 packages of binding. One package of binding contains 2 yards, or 72 inches. Packages of binding Check It Out! Example 1 Continued Daryl needs approximately 191.3 inches of binding. Add these lengths to find the perimeter of the kite.ģ Solve perimeter of PQRS = Check It Out! Example 1 Continued Pyth. ![]() Use the Pythagorean Theorem and the properties of kites to find the unknown side lengths. ![]() Make a Plan 2 Check It Out! Example 1 Continued The diagonals of a kite are perpendicular, so the four triangles are right triangles.
