tanGram

This is an ancient puzzle that originated in China, consisting of 7 shapes.
It has 2 big triangles, one medium triangle, two small triangles, one
square and one parallelogram. By rearranging the tangram pieces to
create different shapes and figures, one can develop better awareness of

how shapes fit together in a space.
making Various shapes using tangrams

Square Rectangle

Parallelogram Triangle

The above mathematical shapes are made using all 7 pieces of tangram, but it is not
always necessary to use all the pieces. You can use at least two shapes to a maximum of
7 pieces to construct any shape be it mathematical or other.
Here, a trapezoid is made using 4 different pieces and a triangle using 2 and 4 pieces
respectively.
