7. Can we have a rotational symmetry of order more than 1 whose angle of rotation is:

            (i)\: 45^{o}?                 (ii)\: 17^{o}?

We can observe that the angle of rotation is the factor of 360 \degree,then it will have rotational symmetry of order more than 1.

(i) 45^{o} is a factor of 360 \degree so the figure having its angle of rotation as 45^{o} will have rotational symmetry of order more than 1.

(ii)17^{o} is not a factor of 360 \degree so the figure having its angle of rotation as 17^{o} will not have rotational symmetry of order more than 1.
