It is extremely important to recognize that 52 o can be obtained by giving the pyramid a height (H) equal to half the side (S), divided by p (pi) and multiplied by four. In the case of the Great Pyramid of Giza, this corresponds to (754 feet to a side divided by 2 equals 377, which in turn is divided by 3.14 to yield 120, the latter which is multiplied by 4 to obtain 480 feet). The angle of 43.5 o is obtained by the same formula, except by multiplying times 3 instead of 4 . The Pyramid of the Sun uses the 43.5 o angle initially, but then is stepped into the center four times, so that it's ultimate height becomes only 250 feet.]
