Rectangular symmetry, also known as rectic symmetry or digonal symmetry and notated K₂, 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

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

Convex polytopes with K₂ symmetry

• Rectangle (isogonal)/Rhombus (isotopic)
