Add Yahoo as a preferred source to see more of our stories on Google. A high school teacher didn't expect a solution when she set a 2,000-year-old Pythagorean Theorem problem in front of her students.

In this math tutorial, we explore how to find the missing side of a right triangle using the pythagorean theorem. We'll specifically look at examples involving a radical to ensure you can solve ...

But that isn’t quite true: in our lecture we present a new proof of Pythagoras’s Theorem which is based on a fundamental result in trigonometry—the Law of Sines—and we show that the proof is ...
