The Pythagorean Theorem is named for the Greek mathematician Pythagoras.
It uses the equation $${{\mathtt{a}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{b}}}^{{\mathtt{2}}} = {{\mathtt{c}}}^{{\mathtt{2}}}$$ to solve for lengths of a right triangle's sides, given two sides and one unknown.
A and b would be the lengths of the triangle's legs (two shorter sides) and c would be the length of the hypotenuse (longest side, diagonal to legs).
