Pythagoras’ Theorem

Pythagoras’ Theorem

Pythagoras’ Theorem. Hypotenuse - it is the side opposite to the right angle. Pythagoras’ Theorem. a. c. b. For any right-angled triangle, c is the length of the hypotenuse, a and b are the length of the other 2 sides, then. c 2 = a 2 + b 2. Historical Background. Pythagoras’ Theorem.
