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
Original 90 Degrees 180 Degrees 270 Degrees 360Degree
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.
