This particular geometric design hangs totally on the spacing between G1 and G3.
This diagram below gives all the salient angles and measurements , the Giza rectangle as a whole is around 6" bigger than Petries estimations on its width and length.
Angle fractions in decimals
I recently found further measured evidence that G2 is intrinsically linked to the equilateral triangle / circle configuration , as the distance from the center of the triangle to G2's North West corner is exactly 18432" , which is the half measure of one side of the equilateral triangle which measures 36864"
The main diagram
Just adding this Giza diagram showing the overlaid Equilateral Triangle that i say was used to set out the positions of the three main pyramids , it also shows how accurate this Google Earth diagram is in relation to the pyramids, to show how accurate it is when used to measure point to point local locations ive shown the measure from the Equilaterals center to one of its corners, to which geometry dictates it to be 21283.44" , based on a base of 36864"
So measured via Google Earth it gives it as 21283.42" , just 0.02" short from the actual, so i think that dispels the often cry that Google Earth isnt that accurate .
Also, again we can see how the Square root of 3 is built into Giza, via its geometric layout and the actual size of G1
Just another coincidental number of 36518 , or intention ? , close enough to Earth's Tropical year of some 36524 days
This diagram is an update due to more accurate findings.i previously measured it as 36525" , but the geometry dictates that it must be 36518.2",
