The tangram puzzle set is composed of seven pieces. A tangram puzzle set includes: a square, a rhomboid, and the other five pieces are isosceles right triangles of various sizes.
Of these triangular pieces, two are small size triangles, one is a medium sized triangle and two are large size triangles. The area of a large size triangle is twice the area of the medium size triangle. The area of the medium size triangle is twice the area of an small size triangle. The area of the square is also twice the area of an small size triangle. The area of the rhomboid is the same as that of the square. All the angles in these pieces are either 45, 90 or 135 degrees.
Tangrams come from Imperial China and while they are fun in creating tangram scapes and puzzles, they are also a valuable lesson in math.
