How did the ancient Egyptian use geometry?

Answer 1

The ancient Egyptians displayed their considerable grasp of geometry in a number of ways. What is arguably the most obvious is the way geometry was used in the construction of the pyramids and other buildings and monuments. Certainly they laid out their cities using geometric principles. It was Ahmes (actually Ahmose), who left us with a fine approximation of the value of pi from that time. There are other examples, but none with the drama and "recognition value" of the geometric applications in religious architecture and construction first cited. Wikipedia has a bit more posted, and a link to their article can be found below. In other words they used geometry by building pyramids.

Answer 2

Geometry was used in wall or cave paintings they made and found inn everyday objects.
