The order of rotational symmetry denotes the total number of times you can rotate the geometric figure so that its looks exactly the same as the original figure.

Rotational Symmetry – 1

 Original             90 Degrees                 180 Degrees                            270 Degrees                      360 Degree

A rotational symmetry of order 1 means that the shape will look like its original only once you rotated the shape 360 degrees. The arrow you see above has a rotational symmetry of order 1.

Rotational Symmetry - 2

A rotational symmetry of order 2 means that the shape will look like its original every time you rotate it by 180 degrees. The rectangle you see above has a rotational symmetry of order 2.
