Please choose the correct solution to the question: How do you find the angle of rotational symmetry?

Solution1: The angle of rotational symmetry is the smallest angle for which the figure can be rotated to coincide with itself. The order of symmetry is the number of times the figure coincides with itself times 6, as its rotates through 360° . Example: A regular hexagon has rotational symmetry.

Solution2: The angle of rotational symmetry is the smallest angle for which the figure can be rotated to coincide with itself. The order of symmetry is the number of times the figure coincides with itself as its rotates through 360° . Example: A regular hexagon has rotational symmetry.
