Abstract

Pierre de Fermat proved that the area of a Pythagorean triangle is not a perfect square. If he also had a proof of Fermat’s Last Theorem, then he could have easily extended his triangle area proof to show that primitive Pythagorean triangles could not have an area that is a perfect cube or higher power. Because there is no record of this, we might suppose that he did not ultimately accept that he had a valid proof of Fermat’s Last Theorem.
