Can we have a rotational symmetry of order more than 1 for figures whose angle of rotation is
(a) 360°
(b) 22°

Solution:

We know that if angle of rotation is a factor of 360 then the figure will have rotational symmetry of order more than 1. 
1. 360^o  is a factor of 360^o, hence it will have rotational symmetry of order more than 1
2. 22^o is not a factor of 360^o, hence it will not have rotational symmetry of order more than 1
