The right triangle altitude theorem - math problems

The altitude to the hypotenuse is the geometric mean of the two segments of the hypotenuse. Each leg of the right triangle is the mean proportional of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.

h=c1c2


Also known as a geometric mean theorem. The geometric mean theorem is a special case of the chord theorem.
