The four congruent quadrilaterals are joined in such a way that a new and larger square with side r appears. At its center, a square hole appears. He let q be its side. From the construction of the new square, it immediately follows that r2 = p2 + q2. As q = a - b, one sees that p, q and r make up the side of a right angle. This reasoning can be used to arrive at a “dissection” proof for the Pythagorean proposition. According to E. S. ) by Henry Perigal as late as 1873 (Loomis 1968/1972:104). Gerdes considers an arbitrary right triangle with sides p, q and r.

By the time of the Egyptian mace in 3100 BC, various agricultural communities along the banks of the River Nile were united by a Nubian, King Menes, who founded a dynasty of 32 Pharaohs and lasted 3,000 years. For more than half that time, areas of modern Israel and Syria as well as the Nile Valley were part of Egypt.
