So by SAS similarity, we know that triangle CDE is similar to triangle CBA. And just from that, you can get some interesting results. Because then we know that the ratio of this side of the smaller triangle to the longer triangle is also going to be 1/2. Because the other two sides have a ratio of 1/2, and we're dealing with similar …Geometric mean (or mean proportional) appears in two popular theorems regarding right triangles. The geometric mean theorem (or altitude theorem) states that the altitude to the hypotenuse of a right triangle forms two triangles that are similar to each other and to the original triangle.

The Pythagorean Theorem is just a special case of another deeper theorem from Trigonometry called the Law of Cosines. c^2 = a^2 + b^2 -2*a*b*cos (C) where C is the angle opposite to the long side 'c'. When C = pi/2 (or 90 degrees if you insist) cos (90) = 0 and the term containing the cosine vanishes.
