a traditional Japanese geometric puzzle or problem that was historically displayed on wooden tablets called "sangaku" at Shinto shrines and Buddhist temples
What is "sangaku"?
Sangaku is a traditional Japanese geometric puzzle, typically carved on wooden tablets or boards and displayed in temples or shrines. These puzzles often feature intricate shapes, such as circles, triangles, and other polygons, arranged in challenging ways. The objective is to solve complex problems related to these geometric figures, such as finding areas, angles, or relationships between the shapes. Sangaku became popular during the Edo period (1603-1868) and was seen as a way to celebrate mathematics and challenge intellectual abilities. They are a reflection of Japan's historical interest in mathematical creativity and problem-solving.
