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. Think of propeller blades (like below), it makes it easier. For discrete symmetry with multiple symmetry axes through the same point, there are the following possibilities: In addition to an n -fold axis, n perpendicular 2-fold axes: the dihedral groups Dn of order 2 n 4×3-fold and 3×2-fold axes: the rotation group T of order 12 of a regular To learn more, go to Reflection Symmetry. Rotational Symmetry. With Rotational Symmetry, the image is rotated (around a central point) so that it appears 2 or more times. How many times it appears is called the Order. Here are some examples (they were made using Symmetry Artist, and you can try it yourself!) A figure has rotational symmetry if it coincides with itself in a rotation less than 360 degrees. The order of rotation of a figure is the number of times it coincides with itself in a rotation less than 360 degrees. The angle of rotation for a regular figure is 360 divided by the order of rotation. Rotational symmetry, a concept that tends to be difficult for students to grasp. The rotational symmetry anchor chart helps to anchor their learning. Rotational Symmetry anchor chart - would be great in math journals - use a butterfly clip so the students can rotate the shapes Anchor Chart Linky - Teaching With Simplicity

### Rotational symmetry can also be affected by color. An example of this is the yin-yang symbol. If the difference in color between the two halves is neglected, then this symbol has two-fold symmetry and can be turned 180 degrees and appear the same. Similar Articles.
