Answer 2

15)Rotational symmetry of order more than 1 are ) ( ) ( ) (, , , )a b d e ( and ) f ( because in these figures, a complete turn, more than 1 number of times, an object looks exactly the same.

16)(i)If the angle of rotation is 45∘ , then symmetry of order is possible and would be 8 rotations.

(ii)If the angle of rotational is 17∘ , then symmetry of order is not possible because 360∘ is not complete divided by 17∘ .
