In nature we often meet the axial symmetry . It can be found, for example, in flowers and in structure of marine creatures. Axial symmetry is widely used in ornamental design, such patterns are called rosettes.

The figure, which possesses axial symmetry, isn't being changed when rotated around an axis, perpendicular to a plane of the image.

The number of such matching during a complete circular revolution of a figure refers to as as the order of symmetry. The axial symmetry can be expressed by any integer from two ad infinitum. All turns, at which the figure is matched with itself, should be equal, otherwise there will be no complete overlapping.

If the figure has only axial symmetry and not any another, it displays an effect of a rotary movement. In ornaments the rosettes more often possess not only axial, but also mirror symmetry as well. Such forms are more counterbalanced and quiet.
