Today in Geometry we discussed how some numbers were/are considered sacred by various religious traditions. Examples were given from Christian, Muslim, and Buddhist art. Even the ancient Egyptians used some of these holy numbers when approximating the value of pi.

Sandreckoner’s diagram allows us to divide the edge of a square into fractions based on these numbers: into 3, 4, 5, 7, and 11 equal parts.
