A polygon having rotational symmetry of order more than 1 cannot have angle of rotation equal to
90o
120o
125o
36o
For a regular polygon, number of rotational symmetry exactly divides 3600. Since 3600 is not divisible by 1250, hence the answer.
Can we have a rotational symmetry of order more than 1 whose angle of rotation is
(i) 45°?
(ii) 17°?
A figure with angle of rotation as 17∘ has rotational symmetry of order more than 1.
Identify a quadrilateral with a rotational symmetry of order more than 1 but does not have a line symmetry.
