9.5 Symmetry
Line Symmetry: figure can be mapped onto itself across a line(reflection symmetry or axis symmetry)
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)
