Axis Symmetry

A figure in space is said to have axis symmetry if it can be mapped onto itself after a rotation — strictly between 0^(∘) and 360^(∘) — about a line.

As the given example demonstrates, a hexagonal prism can be rotated 60^(∘), 120^(∘), 180^(∘), 240,^(∘) or 300^(∘) about the axis of symmetry l and it would still look the same. It is worth noting that rotating any figure 360^(∘) about any axis will not change how it looks.
