Question

can we have a rotational symmetry of order more than 1 whose angle of rotation is 30 degree? justify your answer.

Answer 1

Dear Student,

It can be observed that if a figure looks symmetrical on rotating by 30°, then it will also look symmetrical on rotating by 60°, 90°, 120°, 150°, 180°......... i.e., further multiples of 30°. Therefore, the figure having its angle of rotation as 30° will have its rotational symmetry of order more than 1.

We hope that this answer solves your query.
Regards.
