Question

can we have a rotational symmetry of order more than one whose angle of rotation is (a) 45 degrees (b) 17 degrees

???​

Answer 1

Answer:

a) Yes

b) No

Step-by-step explanation:

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.

(a) It can be checked that 45° is a factor of 360°. Therefore, the figure having its angle of rotation as 45° will have its rotational symmetry of order more than 1.

(b) 17° is not a factor of 360°. Therefore, the figure having its angle of rotation as 17° will not be having its rotational symmetry of order more than 1.
