**Rectangular symmetry**, also known as **rectic symmetry** or **digonal symmetry** and notated **K _{2}**, is a 2D spherical Coxeter group. It is the symmetry group of the rectangle, with two rotations and two reflections. Any even-sided polygon has this as a subsymmetry.

### Subgroups[edit | edit source]

- Inversion symmetry (normal, maximal)
- Reflection symmetry (normal, maximal)
- Identity symmetry (normal)
