Live Science on MSNHigh school students who came up with 'impossible' proof of Pythagorean theorem discover 9 ...Mathematicians had long thought that using trigonometry to prove the theorem was unworkable, given that the fundamental ...
With two angles and the length of one side of the “triangle”, you can then bung all those numbers into a few trigonometric formulas (the sine rule and Heron’s formula can help) and shazam ...
