The operation of exchanging all points of a mathematical object with their Mirror Images (i.e., reflections in a mirror). Objects which do not change Handedness under reflection are said to be Amphichiral; those that do are said to be Chiral.

If the Plane of reflection is taken as the -Plane, the reflection in 2- or 3-D Space consists of
making the transformation for each point. Consider an arbitrary point and a Plane specified
by the equation
