A square is a two-dimensional hypercube.

Squares are the most common base for two-dimensional manifolds and polyominoes.

Equations

  • Variables:
l ⇒ length of edges of the square
[:x,:y] ⇒ line segment of length lsin(45° + (θ % 90°)√2

Segmentation

The square of side 2 may be segmented into 4× triangle with sides 2, 2×22-1 and angles 2×45°, 90°.
