The Geometry of Giza (cont.) By Edward G. Nightingale
Using the intersection of the South East corner of Khufu and drawing a line vertically to the horizontal center line we determine the base length*of the pyramid. One note at this point, *the full-scale measurement is not the exact base length of the Pyramid of Khufu which is 756 ft. but is completely relevant when the relationship of the elevation of the pyramid base to the elevation of the axis of the circle are taken into account. This will be addressed at a later point and is very important and elegant in its design. We also note that the 45°degree line intersects the center of the northern most satellite pyramid of Khufu.
