For 10 points, name this theorem whose formula is a squared plus b squared equals c squared, and which is used with right triangles.
One extension of this theorem relates the areas of the faces of a shape in three dimensional space and is called de Gua's Theorem. One proof of this theorem makes use of three squares in a figure sometimes called the bride's chair or windmill. This theorem can be obtained from a reduction of (*) Heron's Formula. Its namesake "triples" can be calculated from this theorem's relation of leg lengths to the hypotenuse length.
