The Pythagorean Theorem was founded by Pythagoras. It was regarding the study of right triangles and the relationship between the legs and the hypotenuse. He summarized his discoveries into one formula: A^2 + B^2 = C^2, also known as the Pythagorean Theorem. The theorem helps architects find the correct proportions for the triangles.
In real life, the Pythagorean Theorem is used everyday for architects to check their buildings' proportions and make sure that they can be built. Meaning that the beams fit together and are not oversized or too short. The Theorem is used in matters such as the slant height of a pyramid and the floor plan of a triangular-shaped building.
