Question 107894

Pythagoras' Theorem claims that the sum of (the areas of) two small squares on the sides of a right triangle equals (the area of) the big one.
In algebraic terms, {{{a2 + b2 = c2}}}where {{{c}}} is the hypotenuse while {{{a}}} and {{{b }}}are the legs of the triangle.

The statement of the Theorem was discovered on a Babylonian tablet circa 1900-1600 B.C. The Theorem is {{{reversible}}} which means that a triangle whose sides satisfy {{{a2 + b2 = c2 }}}is necessarily {{{right}}}{{{ angled}}}.{{{ Euclid }}}was the{{{ first}}} to mention and {{{prove}}} this fact.
