A square is a two-dimensional hypercube.
Squares are the most common base for two-dimensional manifolds and polyominoes.
Geometry
Equations
- Variables:
l ⇒ length of edges of the square
- The radial slices θ of a square are:
[: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°.
Use
Square faces are found in these polyhedra on FGwiki:
- Cube (6, 100%)
- Triangular prism (3, 60%)
- Cuboctahedron (6, 43%)
- Truncated octahedron (6, 43%)
- Square antiprism (2, 20%)
- Square pyramid (1, 20%)
- Snub cube (6, 16%)
