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.An explanation of three tests for triangle similarity: side-side-side; side-angle-side; and angle-angle.

All the angles of the squares are congruent and the side lengths are proportional. The corresponding angles of the triangles are all congruent. And the side lengths are all proportional. The SSS similarity criterion says that two triangles are similar if their three corresponding side lengths are in the same ratio. That is, if one triangle has side lengths a, b, c, and the other has side lengths A, B, C, then the triangles are similar if A/a=B/b=C/c. These three ratios are all equal to some constant, called the scale factor. The SSS similarity criterion says that two triangles are similar if their three corresponding side lengths are in the same ratio. That is, if one triangle has side lengths a, b, c, and the other has side lengths A, B, C, then the triangles are similar if A/a=B/b=C/c.
