From Wikipedia, the free encyclopedia. Tangram (Chinese: literally "seven boards of cunning") is a Chinese puzzle. While the tangram is often said to be ancient, its existence has only been verified as far back as 1800. It consists of 7 pieces, called tans, which fit together to form a square; taking the square as the unit: \t* 5 right isosceles triangles \t\to 2 small (legs of 1) \t\to 1 medium size (legs of square root of 2) \t\to 2 large size (legs of 2) \t* 1 square (side of 1) \t* 1 parallelogram (sides of 1 and square root of 2)
