Question

What is the minimum interior angle possible for a regular polygon?

• A. 70°
• B. 60°
• C. 45°
• D. 80°

Answer 1

The correct option is B 60°

Consider a regular polygon having the least number of sides (i.e. an equilateral triangle)

We know that the sum of all the angles of an equilateral triangle = 180°

Let the measure of each angle be x°
So, x + x + x = 180°

3x = 180°

x = 180°$÷$ 3

x = 60°

Thus, the minimum interior angle possible for a regular polygon is 60°
