I'm going to try and explain what I am showing with that drawing.
The large circle drawn from the centre of Khufu's baseline is snapped to the north eastern corner of Khafre's pyramid. It runs through the Khafre mortuary temple and intersects with the line running east, from the south side of the mortuary temple. There is an overlap on this line of 5.4016 inches over a span of 10306.6507 inches(858.887 feet). So that circle is just over 5 inches over the base line of the mortuary temple. There is a big questionmark here. What are the dimensions of the mortuary temple from pyramid centreline? The mortuary temple measurements I have are from a French Architect, but every dimension I have seen on the web has given a different reading. So does the circle from the GP intersect perfectly with the baseline of Khafre mortuary temple?
The northern edge of the Khafre causeway would meet the interior north western corner of the mortuary temple, if the line were carried on. The northern edge of the causeway is running at a tangent from the circle that is centred on Khufu's baseline. The circle does not overlap the causeway, it just touches the northern edge.
The circle that is centred on Khafre's northeastern corner and is snapped to a line runnung west from Khufu's baseline. Overlaps the Khafre mortuary temple baseline by 12.8486 inches. Again I state that I have no accurate data for the dimensions of that temple other than the drawings of a French Architect.
The two circles centred on the north and southeast corners of Khafre's pyramid, and the one centred at the back edge of the mortuary temple/pyramid centreline, intersect 9.939 feet east of the mortuary temple. That intersection is also 12.64 inches south of an easterly line drawn on the outside of the northern wall of the temple, and 12.64 inches north of an east line from the outside of the south wall. There might well be no significance in those 3 circles, but I just thought I would add them in.
As to the angle of Khufu's causeway being due to a change in terrain. Why should a change in terrain result in a change of angle in the causeway? The causeway is said to have been built up to the level of the plateau, so a change in topography was not a problem, and is unlikely to have resulted in an angle change in the causeway. Is it dismissible that this particular causeway reflects the same angle as the northwestern corners of the 3 pyramids?
Now the question is, if Khufus pyramid and causway were built first, were the two other main pyramids aligned to reflect this causeway angle of 160.68°, or was Khufu's causeway built to reflect the angle of the northwest corners of the 3 pyramids?
That would mean that his causeway was built after the 2 other main giza pyramids, wouldn't it?
Even if you argue that Khufu's causeway does have a change of angle due to topography changes, it does not explain why the north west corners of the pyramids have the same angle. It can not be put down to random chance.</HTML>
