Buddha loves geometry… at least according to Japanese?
Sangaku (or San Gaku) are Japanese geometric puzzles carved on wood tablets that are used as offerings at Shinto shrines or Buddhist temples. The puzzles consist of circles and triangles utilizing concepts from Euclidean geometry, and they typically ask the solver to find the relationship between the circles and triangles. In this particular Sangaku, we will be looking at three circles placed inside a particular right triangle, and will investigate the radii and areas of the circles.
