Tangrams

Tangram is a Chinese dissection puzzle which uses 7 geometric shapes called "tans".  The seven shapes are: 2 large triangles, 2 small triangles, 1 medium triangle, 1 small square and 1 parallelogram.


The objective of the puzzle is to make a given shape with all seven tans without overlapping them.  You can enjoy the game of tangrams alone or with a friend.

A Bit Of Tangram History

The first book of tangrams was published in China in 1913 and by 1818 tangrams were popularized all over Europe.
It is unclear when the tangrams originated.  There are few versions of the origin of the name:
1.   Some believe they were created during the Tang Dynasty which was ruling China in 618 A.D. to 907 A.D.
2.   There is a story about man named Tan who supposedly dropped ceramic tile and by trying to put it together came up with the idea of a puzzle,
3.   There is believe that name came from an old English word "trangam", which means "puzzle" or "trinket",
4.   There is also theory that Tangrams are named after Tanka people who lived in southern China and Hong Kong.
