RIGHT TRIANGLE PROPORTIONS How many right triangles do you see?

Mean proportional (A.K.A. GEOMETRIC MEAN) WHEN THE MEANS IN A PROPORTION ARE EQUAL.

There are 2 cases – you must be able recognize which to use and when When an altitude is drawn to the hypotenuse of a right triangle, it divides the hypotenuse proportionally. Follow the formats on the following 2 pages when setting up your proportion.

The altitude Proportion Use this format when you have or are looking for the altitude.

The leg proportion Use either of these 2 formats when you have the leg or are looking for the leg (and the hypotenuse is involved):
