Question
How many angles of rotation a regular polygon will have if it has ‘n’ sides?
Answer: Option B
:
B
Angles of rotation of a regular polygon with ‘n’ sides = Y = n – 1
This is because the last rotation, i.e. 360∘ is not counted as an angle of rotation. If it was counted as an angle of rotation, every object would have an angle of rotation.
So, angles of rotation for a square are 90∘, 180∘ and 270∘. It’s only 3, not 4.
