1. The geometric mean of two positive numbers a and b is .
2. In a right triangle, the altitude drawn to the hypotenuse creates three triangles.
3. The length of the altitude to the hypotenuse of a right triangle is the geometric mean between the two of the hypotenuse.
4. Find the value of x in the diagram below.
5. A right triangle has an altitude drawn to its hypotenuse, dividing it into segments of length 3 cm and 12 cm. What is the length of the altitude?
6. Find the value of y in the diagram below.
7. The hypotenuse of a right triangle is 20 units long. If one leg is 8 units long, and the adjacent segment of the hypotenuse is 4 units, find the length of the other leg using the geometric mean.
