Tangram

Invented in China approximately 200 years ago, a tangram is a two-dimensional re-arrangement puzzle created by cutting a square into seven pieces — seven geometric shapes called “tans”.

What are the seven shapes in a tangram? Each tangram puzzle contains the following:

• 2 large right triangles
• 1 medium-sized right triangle
• 2 small right triangles
• 1 small square
• 1 parallelogram

Arranged correctly, these tangram shapes can be fitted together as a large square, rectangle, or triangle. They can also be arranged in a variety of complex shapes, including fanciful ones (like the rabbit illustrated here).
