A regular hexagon has rotational symmetry of order 6, meaning it can be rotated in multiples of \(360^\circ / 6 = 60^\circ\).
The degrees of rotation that will map a regular hexagon onto itself are:
- \(0^\circ\)
- \(60^\circ\)
- \(120^\circ\)
- \(180^\circ\)
- \(240^\circ\)
- \(300^\circ\)
Excluding \(360^\circ\), the largest degree of rotation that would turn a regular hexagon onto itself is \(300^\circ\).
Thus, a rotation of 300 degrees would turn a regular hexagon on itself.
