Pythagoras developed a formula to find the lengths of the sides of any right triangle. Pythagoras Discovered that if he treated each side of a right triangle as a square (see figure 1) the two smallest squares areas when added together equal the area of the larger square. If you are familiar with the trigonometric basics, you can use, e.g. the sine and cosine of 30° to find out the others sides lengths: a/c = sin(30°) = 1/2 so c = 2a. b/c = sin(60°) = √3/2 so b = c√3/2 = a√3. Also, if you know two sides of the triangle, you can find the third one from the Pythagorean theorem. However, the methods ...
