I have to solve this by setting up a proportion using either one of these theorems: 1. When an altitude is drawn to the hypotenuse of a right triangle, then the altitude is the geometric mean between the parts of the hypotenuse. (Part-altitude-altitude-part) Or 2. When an altitude is drawn to the hypotenuse of a right triangle, then each original leg is the geometric mean between the hypotenuse and the part of the hypotenuse adjacent to the leg. (Part-leg-leg-whole)

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
