A mathematics course from the Zep Tepi era, where we plan and analyse a large building site, showing how the design mirrors the stars. A simple and elegant explanation of how Giza, with six main pyramids, was laid out, using √2, √3, √5, π and φ. The design incorporates the necessary elements for squaring the circle, area-wise. The design matches the heavens around 55.5k BCE. This could force a rethink of at least the history of mathematics, if not the broader human timeline. This effectively solves the puzzle of how Giza was laid out.Version 1.2.0: Fixed some typos. Added new π and e diagrams. Added formulas for relation between P1, P2 and P3 base sizes. Removed "A map of Khufu?" section, it is wrong and I have a better idea. Added altern...
