Question

square is not a regular polygon​

Answer 1

Answer:

So, all the sides are not equal to each other. Similarly, among the four angles i.e., ∠ABC, ∠BCD, ∠CDA and ∠DAB where the opposite angles are equal i.e., ∠ABC = ∠CDA and ∠BCD = ∠DAB. So, all the angles are not equal to each other. Therefore, a square is an irregular polygon.
