Tangram

Tangram is an ancient Chinese puzzle. It is a dissection puzzle consisting of seven flat pieces, which are put together to form shapes.

Square

Like most sets, this wooden tangram is stored in the square configuration by Shinainai.

Pieces

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 (hypotenuse 1, sides √2/2, area 1/4)
1 medium right triangle (hypotenuse √2/2, sides 1/2, area 1/8)
2 small right triangles (hypotenuse 1/2, sides √2/4, area 1/16)
1 square (sides √2/4, area 1/8)
1 parallelogram (sides of 1/2 and √2/4, area 1/8)

Code

Shinainai writes some HTML to display a tangram.
