RotationIn 2D, a transformation of the whole plane which turns about a fixed point, the centre of rotation. A is specified by a centre and an (anticlockwise) angle. |
Rotation SymmetryA 2D shape has rotation symmetry about a point if an identical-looking shape in the same position is produced by a rotation through some angle greater than 0 degrees and less than 360 degrees. A 2D shape with rotation symmetry has rotation symmetry of order n when n is the largest positive integer for which a rotation of 360/n degrees produces an identical-looking shape in the same position. |
