The Geometry of Giza (cont.) By Edward G. Nightingale
As we can see the 40°degree and the 33°degree angled lines intersect the South West and North West corners of the Pyramid of Menkaure. By drawing a circle with its axis at the center of the main circle and its radius equal to the distance from the main circles axis the North East corner of the Pyramid of Khufu, the radius of this circle determines the distance of the Western face of the Pyarmid of Menkaure from the horizontal South to North centerline. This particular circle diameter will also be relevant at a later point when dealing with the Phi Ratio and is explained in depth in the Giza Template.
