Find the number of sides in a regular polygon, if its interior angle is equal to exterior angle.
Question
Find the number of sides in a regular polygon,
if its interior angle is equal to exterior angle.
Solution
Sure, here is the step by step solution:
-
We know that the sum of the interior and exterior angles of a polygon is 180 degrees.
-
If the interior angle is equal to the exterior angle, then each of them is 180/2 = 90 degrees.
-
The formula to find the number of sides in a polygon using the exterior angle is: n = 360/Exterior Angle.
-
Substituting the value of the exterior angle, we get: n = 360/90 = 4.
So, the polygon is a quadrilateral, which means it has 4 sides.
