How to solve a regular polygon

WebThe order of a rotational symmetry of a regular polygon = number of sides = n . Also, the angle of rotational symmetry of a regular polygon = 360 ∘ n. For example, a square has 4 sides. So, the order of rotational symmetry = 4. Angle of rotation = 360 4 = 90 ∘. This means when we rotate the square 4 times at an angle of 90 ∘, we will get ...
