"...What records indicate clearly..?
"...What mathematical records DO indicate that other methods were used..?

Anthony:

If you cannot supply the evidence you claim (IV dynasty didn't understand the pi ratio) and you are only working on presumptions in books using your reading skills that you have indicated to this group over the past several days then you are digging a deeper hole for yourself to fall into.

You write of professional researchers...now try implement think/act like one.

This is not a competition of who is right or wrong...it's a presentation of technical finds at the Giza site using simple geometry and mathematics.

Time to use that old math book of yours...intro to geometry.

Also...I believe you have failed to understand the purpose of that ratio in the last illustration I posted for you.

Best.
