The right triangle altitude theorem - math problemsThe 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.
Also known as a geometric mean theorem. Geometric mean theorem is a special case of the chord theorem.
