The smallest angle of rotational symmetry will be "45°".
Regular octagon:
- It has eight sides of the same length as well as eight identical angles. This arrangement devised the angle of rotation into 360° movement.
then,
→ The smallest angle will be:
= \(\frac{360}{8}\)
= \(45^{\circ}\)
We can say that the octagon returns its originating octagon just about every 45 degrees rotational so that an octagon does indeed have a rotary symmetry ordering of eight.
Thus the above answer is correct.
