The seven pieces
The two large triangles and the two small ones are right isosceles. Every edge length is a multiple of the smallest triangle’s leg, which is why the seven pieces fit together exactly.
| Piece | Edges (units) | Share of square |
|---|---|---|
| Large triangle | 4, 2.83, 2.83 | 25.00% |
| Large triangle | 2.83, 2.83, 4 | 25.00% |

| Square | 1.41, 1.41, 1.41, 1.41 | 12.50% |
| Parallelogram | 1.41, 2, 1.41, 2 | 12.50% |

About this tool
A tangram is the seven-piece dissection of a square: two large right triangles, one medium triangle, two small triangles, a square and a parallelogram. This generator draws them at correct proportions so the printed set can actually form the square, and lets you try assembling it yourself.
Everything is drawn and measured locally in your browser — no uploads, no accounts, and your assembly is never sent anywhere.
