Rotation
Rotation means turning around a fixed point. A wheel rotates about its centre. Rotation: 90ยฐ (quarter turn), 180ยฐ (half turn), 270ยฐ (three-quarter turn), 360ยฐ (full turn โ back to start). A square looks the same after rotating 90ยฐ, 180ยฐ, 270ยฐ or 360ยฐ โ it has rotational symmetry of order 4. A circle looks the same after any rotation โ infinite symmetry.
