Sangaku, also known as "sangaku", refers to a traditional form of mathematical puzzle originating in Japan during the Edo period (1603-1868). These puzzles were typically inscribed on wooden tablets and hung in Shinto shrines and Buddhist temples. Sangaku often featured geometric problems involving circles, triangles, and other shapes, and involved solving for distances, angles, and areas.
