Question

How many sides does a regular polygon have if each of its interior angles is 120 degree?​

Answer 1

Answer:

6

Answer. if each interior angle is 120 then each exterior angle will 60. As we know that sum of exterior angle of polygon =360, side =360/60=6 . the number of sides=6.

Answer 2

Answer:

Step-by-step explanation:

Each interior angle =120°

Each exterior angle =60°

Sum of angles =360°

No of sides of a regular polygon =sum of ext angle /each ext angle =360°/60°=6

Therefore there are 6 sides in a polygon with each interior angle 120°
