A set of tangrams contains seven pieces: 2 large triangles, 1 medium triangle, 2 small triangles, a square, and a parallelogram. They are used like jigsaw puzzle pieces to form stylized silhouette pictures.

To make a set of tangrams, cut a square in the seven pieces as shown. The large triangles are double the dimensions of the small triangles. The two small triangles can be used to form the square, the parallelogram, or the medium triangle. The pieces should be finished the same way on both sides because you can use the pieces both right-side-up and upside-down.

Arrange the seven pieces to form silhouettes. For example, form a square like the one on the left above. A tangram puzzle presents you with a silhouette made from the tangram pieces and asks you figure out how it was made. Try forming the following shapes using all seven tangrams.
