Question

find the number of sides in regular polygons if it has angle is equal to 90​

Answer 1

Answer:

Therefore, a regular polygon with each interior angle of 90∘will have 4 sides. Therefore, a regular polygon with each interior angle of 108∘will have 5 sides.

Answer 2

Answer:

the least number of angles a polygon can have are 3 i.e a triangle and the sum of angles in a triangle is 180. So the statement of your question as far as im guessing is not correct. The formula for finding the sides however is

(n -2)x180 = sum of all angles, where n is the number of sides of polygon
