Babylonian Geometrical Problem Tablet

Clay tablet with geometrical problems accompanied by diagrams

Tablet BM 15285, held by the British Museum, has been instrumental in the understanding of Old Babylonian line geometry. It consists of 40 problems with diagrams but no solutions. A third of the tablet is missing.

Babylonian Geometrical Problem Tablet

This tablet, dated to around 1900–1600 BCE, contains problems involving figures drawn inside squares. The problems are ordered by increasing complexity. The first 12 problems concern squares, circles and right triangles; many of the remainder consider more complicated figures.
