Geometric Mean Vocabulary
#1 Finding the Geometric Mean • Find the geometric mean of 15 and 20.
Corollary 1 to Theorem 8-3 The length of the altitude to the hypotenuse of a right triangle is the geometric mean of the lengths of the segments of the hypotenuse. C A B D
Corollary 2 to Theorem 8-3 The altitude to the hypotenuse of a right triangle separates the hypotenuse so that the length of each leg of the triangle is the geometric mean of the length of the adjacent hypotenuse segment and the length of the hypotenuse. C A B D
#2 • Solve for x and y. 4 12 x y 4 y x y 12 x 16
