Chirality in three dimensions Pair of chiral dice (enantiomorphs) In three dimensions, every figure that possesses a mirror plane of symmetry S 1 , an inversion center of symmetry S 2 , or a higher improper rotation (rotoreflection) S n axis of symmetry [4] is achiral. See more In geometry, a figure is chiral (and said to have chirality) if it is not identical to its mirror image, or, more precisely, if it cannot be mapped to its mirror image by rotations and translations alone. An object that is not chiral is … See more A figure is achiral if and only if its symmetry group contains at least one orientation-reversing isometry.
