1. Right Triangles and Trigonometry
Chapter 8

2. 8.1 Geometric Mean Geometric mean:
Ex: Find the geometric mean between 5 and 45
Ex: Find the geometric mean between 8 and 10

3. 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

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

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

6. Find the geometric mean between

7. Find c, d, and e.

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