a 2 + b 2 = c 2. Remember that from high school math class? That's the Pythagorean theorem, which shows that in a right triangle, where the shorter legs are a and b, the sum of their squares is equal ...

In this triangle \(a^2 = b^2 + c^2\) and angle \(A\) is a right angle. Pythagoras' theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.

Learn about the Pythagorean theorem. The Pythagoras theorem is a fundamental relation among the three sides of a right ...

A medical researcher has found the 2,500 year-old Pythagoras theorem could be the most effective way to identify the point at which a patient’s health begins to improve. A medical researcher at the ...
