The Geometry of Giza (cont.)
By Edward G. Nightingale

Our last step was to divide the circle using proportion, if we add the three numbers that are given in the last step, 4,3 and 2 we have the sum of 9 (4+3+2=9). To see if the number 9 has any relevance to the circle and structure alignments we have several options. We can use the number 9 to divide the circles circumference, its radius, or its diameter. A note here is that this specific geometry also allows the circumference of the circle to be divided by 9 and is covered in depth in The Giza Template.
