Proving triangle similarity edgenuity.
JohnWmAustin. 9 years ago. 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.
