8.1 Geometric Mean Geometric mean: Ex: Find the geometric mean between 5 and 45 Ex: Find the geometric mean between 8 and 10

If an altitude is drawn from the right angle of a right triangle, then the two new triangles and the original triangle are all similar. B A C D

The altitude from a right angle of a right triangle is the geometric mean of the two hypotenuse segments B Ex: A C D

The leg of the triangle is the geometric mean of the hypotenuse and the segment of the hypotenuse adjacent B Ex: A C D

Find the geometric mean between

Find c, d, and e.

Find e and f . (round to the nearest tenth if necessary)
