Question

In a regular polygon of 'n' sides, the interior angle is equal to the exterior angle. Find the value of n.

• A. 3
• B. 4
• C. 5
• D. 6

Answer 1

The correct option is B

4

Let interior angle = i° and exterior ngle = e°

We know, i + e = 180°

But it is given that i = e

Therefore, 2e° = 180°

e° = 90°

$n=\frac{360°}{e°}$

$n=\frac{360°}{90°}$

n = 4
