The 13 pages that link to Rotational symmetry, each with the reason it gives.

• SphereRelated: Every rotation about the sphere’s center leaves its surface unchanged.

• Quantum numberRelated: Rotational symmetry underlies angular-momentum labels and their degeneracies.

• Equilateral triangleRelated: Rotating it by 120 or 240 degrees leaves its outline unchanged.

• Regular polygonRelated: A regular n-gon matches itself after each rotation by 360° divided by n.

• TessellationRelated: Rotations around tile vertices help produce repeating arrangements.

• RectangleRelated: A half-turn about its center maps every rectangle onto itself.

• SquareRelated: A square maps onto itself under rotations by 90-degree increments about its center.

• Central forceRelated: A central potential is unchanged by rotations about its center.

• Conserved quantityRelated: Its continuous form yields conservation of angular momentum.

• Surface of revolutionRelated: A full revolution gives the surface continuous rotational symmetry.
