Axial symmetry is symmetry around an axis; an object is axially symmetric if its appearance is unchanged if rotated around an axis.[1] For example, a baseball bat without trademark or other design, or a plain white tea saucer, looks the same if it is rotated by any angle about the line passing lengthwise through its center, so it is axially symmetric.

In two-dimensional geometry, a rotation around an axis is the same thing as a reflection, and axial symmetry is the same thing as reflection symmetry.
