[Math Lair] Symmetry

Math Lair Home > Topics > Symmetry

In mathematics, a figure possessing symmetry can be subjected to certain operations which leave the whole unchanged. The letters A and B have bilateral symmetry by vertical and horizontal reflection respectively. The letter Z is symmetrical for a rotation through 180°. For mathematical convenience the identity operation, leaving the figure unchanged, is included in the list of symmetrical operations, so that even a completely irregular figure has this symmetry.
