When a shape is rotated about its centre, if it comes to rest in a position and looks exactly like the original, then it has rotational<span> symmetry. </span>rotational<span> symmetry</span>order). This means that a regular hexagon has 6 sides, 6 lines of symmetry and anorder<span> of </span>rotational<span> symmetry of 6.</span>
