The tangram puzzle consists of seven flat pieces and a collection of simple outline diagrams or silhouettes. The pieces—which form a dissection of a square—consist of two large triangles, one medium triangle, two small triangles, one square and one parallelogram, and they can be made of wood, ivory, metal or some other material. The diagrams can be pictures of objects, landscapes, animals or even human figures in various positions. The objective of the puzzle is to place all seven pieces on a flat surface (without any pieces overlapping) to form the same shape as one of the diagrams.
One day we practised Tangram and learnt how to build some figures and learnt some related words to each figure we did.
