Thanks for that. I have performed the same operation with many different Giza plan drawings over the years, some yielding slightly different results than others but in all you can observe the very obvious geometric relationship between G1 & G3 and then also G2 when its is centered on the Al Nilam point on the ground plan. Even the drawing you just posted shows this obvious G1-G3 relationship:
The point is this - slightly moving G1 or G3 (or the G3 Queens) in any direction and this relationship breaks down (i.e. becomes like G2). Change the shapes of these bases slightly and, again, the geometric relationship becomes much less compelling. This is to say that if you created two squares (or almost square) out of some card and placed these randomly on a table then it is becomes very difficult indeed to observe anything close to the relationship we observe between the pyramids at Giza. And almost impossible when you introduce a third element (G2).
This can only come about via a unified, homogeneous underlying design.
