Rules of the tangram puzzle
Coming from China (read its brief history), this logic game brings the mathematical thought of Asia and incorporates it with bright colours and charming figures.
A tangram puzzle focuses on the objective to rearrange the seven separate pieces into a complete image of various shapes (in outline or silhouette only).
The classic rules are simple : all tangram pieces (or tans) must be used, they must lay flat, all must touch and none may overlap.

What does a set of tangrams consist of ?
Tangrams shapes are geometric. A complete set is formed from seven polygonal flat pieces.
In a tangram puzzle set there is :
- 5 isosceles triangles of various sizes (2 large congruent triangles; 1 medium-size right triangle; 2 small congruent triangles).
- 1 square
- 1 parallelogram (the only tangram shape that may need to be flipped when forming certain figures).
The seven individual tangram pieces are called tans.
History of Tangram
Tangram puzzles are thought to have originated in China in the Tang Dynasty of the Middle Ages, although some claim that they are over 4000 years old. This rich history of applied gaming found its way to Europe in the early 19th Century.
Finding popularity with those eager to exercise their brain power in an original way, the puzzles took their place as a prestigiously educational form of entertainment.
