The tangram is a dissection puzzle consisting of seven flat shapes, called tans, which are put
together to form shapes. The objective of the puzzle is to form a specific shape
(given only an outline or silhouette) using all seven pieces, which may not overlap.
It was originally invented in China and brought to America in 1815.
