The next number is the rotational symmetry, as given above.

The name of this model comes from its rotational symmetry.

We consider this problem for a body with rotational symmetry fixed in the centre of mass.

In general a parallelogon has 180-degree rotational symmetry around its center.

The first piece to be placed possesses 180 degree rotational symmetry.

The whale had rotational symmetry; of course it would spin.

Note: The example is not an example of rotational symmetry.

The table need not be circular, but it must possess 180 degree rotational symmetry.

The rotational symmetry about a vertical axis can be clearly seen in this picture.

Thus, for example, wallpaper and crystals cannot have 8-fold rotational symmetry.

The duocylinder has rotational symmetry in both of these planes.

Because of this and rotational symmetry, all the red segments in Fig 8 have the same length.

Thus 5-fold rotational symmetry cannot be eliminated by an argument missing either of those assumptions.

See also rotational symmetry with respect to any angle.

The monomers surround a central channel with 3-fold rotational symmetry.

If has a center of rotational symmetry , then .

It has point symmetry, also known as rotational symmetry of order 2.

The crystal is then said to have a twofold rotational symmetry about this axis.

A circle is said to be symmetric under rotation or to have rotational symmetry.

Both of these types of figures will contain rotational symmetry.

A simple and fast algorithm for recovery of rotational symmetry parameters has been developed in this paper.

Good dispersion and rotational symmetry was also observed on this lattice.

Chiral point groups must therefore only contain (purely) rotational symmetry.

An object may have more than one rotational symmetry; for instance, if reflections or turning it over are not counted.

Rotational symmetry emerges spontaneously at large distances just because there aren't very many low order terms.
