Tangrams are a seven-piece geometric puzzle that dates back at least to the Song Dynasty in China (about 1100 AD). Below[1] you will find the seven puzzle pieces. Make a careful copy (a photocopy or printout is best), cut out the puzzle pieces, and then use them to solve the problems in this section.
Whenever you solve a tangram puzzle, your job is to use all seven pieces to form the shape. They should fit together like puzzle pieces, sitting flat on the table; no overlapping of the pieces is allowed.
You can trace around your solutions to remember what you have done and to have a record of your work.
Use your tangram pieces to build the following designs[2]. How many can you make?
(These are all separate challenges. Each one requires all seven pieces. Once you solve one, trace your solution. Then try to solve another one.)
