Feb 28­7:17 AM

Rotational Symmetry: figure can be mapped onto itself by a rotation of 00 to 3600 about the center of the figure(radial symmetry)

Order of Symmetry: number of time it maps onto itself as it rotates from 00 to 3600

Center of Symmetry: center of the figure (point of symmetry)

Magnitude of Symmetry: smallest angle that the figure can be rotated onto itself (angle of rotation)
