Without doubt the Tangram is the most popular put-together puzzle, and one
of the most well known puzzles ever. The origins of the Tangram are
unknown, but the earliest references date back to the beginning of the
19th century, China. That's why the puzzle is also known as the Chinese
puzzle. The puzzle consists of seven pieces - tans - obtained by dividing
a square as shown in the illustration. To play with the Tangram simply
print all the seven pieces and then cut them out. Now you're able to
arrange them in many different ways making an infinite number of nice,
fun, and sometimes very puzzling figures. For every figure you have to use
all the seven tans. You're allowed to rotate the pieces as you wish, and
even flip them over. But you can't overlap the pieces. We've chosen just a
few most popular figures that you may assemble using all the seven tans.
They will give you a good taste of the puzzle.
