Uit Wikipedia, die vrye ensiklopedie. Tangram (Sjinees vir "sewe stukke slimheid") is 'n Sjinese legkaart. Mense sê dikwels dat die tangram uit die antieke tyd kom, maar die bestaan daarvan kan net tot so vroeg as 1800 geverifieer word. Dit bestaan uit 7 stukke, genaamd 'tans', wat saampas in 'n vierkant. Met die vierkant as 'n eenheid: \t* 5 regte, gelykbenige driehoeke \t\to 2 klein (bene van 1) \t\to 1 mediumgrootte (bene van vierkantswortel van 2) \t\to 2 groot (bene van 2) \t* 1 vierkant (kan van 1) \t* 1 parallelogram (kante van 1 en vierkantswortel van 2)
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)
