What is a tangram? Tangrams are puzzles made with seven geometrical pieces—five triangles (2 small, 1 medium, 2 large), a rhomboid, and a square. They are all cut from one large square. The trick is to arrange the pieces to form the silhouettes—people, animals, and objects printed on the page. Solutions, if needed are provided in the back of the book. 120 puzzles with solutions and two complete sets of heavy cardboard tangrams.
