| bilateral symmetry |
symmetry about a fixed line in a plane (line of symmetry). Each point P of the symmetrical configuration has an image point P' such that the line of symmetry is the perpendicular bisector of PP'. Points on the line transform into themselves. In three dimensions bilateral symmetry can exist about a fixed plane.
