Terrific Tangram

Tangram never looked the same anymore. Today i went beyond discovering how to solve the different silhouette using all the seven pieces i've got! 

Just in case you are wondering what tangram is...

It is one of the most popular dissection puzzles in the world. A Chinese psychologist has termed the tangram "the earliest psychological test in the world", albeit one made for entertainment rather than analysis.

Choosing a unit of measurement so that the seven pieces can be assembled to form a square of side one unit and having area one square unit, the seven pieces are:

• 2 large right triangles 

• 1 medium right triangle 

• 2 small right triangle 

• 1 square 

• 1 parallelogram 

Of these seven pieces, the parallelogram is unique in that it has no reflection symmetry but only rotational symmetry, and so its mirror image can be obtained only by flipping it over. Thus, it is the only piece that may need to be flipped when forming certain shapes. Isn't that amazing?
