Fun Fact
Pizza Theorem origin: In 1967, mathematician L. J. Upton proposed the Pizza Theorem as a puzzle in a mathematics magazine.
Glossary
pizza theorem (noun)
A geometric theorem stating that partitioning a disk with equal-angled cuts through any interior point yields alternating sectors of equal total area. L.J. Upton first proposed this geometric challenge in 1967 within the Mathematics Magazine.
