Write the order of rotational symmetry and the angle of rotation for the following diagram.

Asked by Topperlearning User | 15th Dec, 2013, 09:28: AM

Expert Answer:

After rotating through 180o, it gives the same image, so the angle of rotation is 180o.

Also through a complete turn it looks similar 2 times at each 180o turn. Hence the order of rotational symmetry is 2.
