It divides the parabola into mirror images. This type of symmetry is called reflective symmetry. Specifically, symmetry refers to a correspondence of body parts, in size, shape, and relative position, on opposite sides of a dividing line or distributed around a central point or axis.

Symmetry is only applied to a feature of size (feature with a dimension) and requires having a datum plane to establish the symmetry.
