How many order of rotational symmetry does a circle and oval have.
Asked by Sanjay | 13 Sep, 2016, 11:55: AM
answered-by-expert Expert Answer
A shape has Rotational Symmetry when it still looks the same after a rotation.
A circle has an infinite 'order of rotational symmetry'. That is, a circle will always fit into its original outline, regardless of how many times it is rotated.
 
On the other hand, the order of rotation of a rotational symmetry is 2.
