Question
Can we have a rotational symmetry of order more than 1 whose angle of rotation is 17°?

Solution
It can be observed that if the angle of rotation of a figure is a factor of 360°, then it will have a rotational symmetry of order more than 1.
17° is not a factor of 360°. Therefore, the figure having an angle of rotation as 17° will not be having its rotational symmetry of order more than 1.
