What is known?
What is unknown?
The figures have rotational symmetry of order more than \(1\).
To solve this question, remember the concept of rotational symmetry. Rotational symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appears the same. The order of symmetry is the number of positions the object looks the same in a \(360^\circ\) rotation.
Rotational symmetry of order more than one are: (a), (b), (c), (d), (e) and (f) because in these figures, in a complete turn more than one number of times an object looks exactly the same.
