Rotational symmetry

Rotational symmetry is a shape that if it is rotated into certain angles, it matches with the original shape of it. Rotational symmetry is different to line symmetry because the line symmetry is a reflection, not a rotation. You check if the shape has a symmetry and try to visualise what happens if it gets rotated.
