Segment CD is the altitude of right triangle ABC. All three triangles in the figure, ABC, CBD, and ACD, are similar to each other.
If p² = xy, then p is the geometric mean of x and y.
In this problem, you will work backwards to outline a proof why the height h of altitude CD is the geometric mean of x and y.
2a. Set up a proportion that will cross-multiply into the equation h² = xy. (2 points)
