The pyramids of Cheops
are each comprised of four triangular planes set about a square base.
in a two dimensional world, pyramids may be reduced to a three sides figure or triangle.
Here, a large base and three sides also conveys a diminishing relationship between the apex and the base of any process.
The apex or top represents the outcome, and the base or bottom stands for the underlying supporting parts of the process; in this case turning grain into bread, or digestible food.
