# What does rotational symmetry mean?

Rotational symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appear the same. The order of symmetry is the number of positions the object looks the same in a 360-degree rotation.

Herein, what is rotational symmetry give examples?

Many shapes have rotational symmetry, such as rectangles, squares, circles, and all regular polygons. Choose an object and rotate it up to 180 degrees around its center. If at any point the object appears exactly like it did before the rotation, then the object has rotational symmetry.

Also Know, what is rotational symmetry geometry? A figure has rotational symmetry if it can be rotated by an angle between 0° and 360° so that the image coincides with the preimage. The angle of rotational symmetry is the smallest angle for which the figure can be rotated to coincide with itself.

In this manner, what happens rotational symmetry?

A shape has Rotational Symmetry when it still looks the same after some rotation (of less than one full turn). How many times it matches as we go once around is called the Order.

Does the letter N have rotational symmetry?

Capital letters that have rotational symmetry are: Z, S, H, N and O. Examples of letters with a horizontal line of symmetry include B, C, D, E, H, I, K, O, S and X.
