Question

A regular pentagon will have-

• A. 4 sides of equal length
• B. Each angle of 108^o
• C. Each angle of 106^o
• D. 6 sides

Answer 1

The correct option is B

Each angle of 108^o

We know that the sum of the interior angles of a polygon of n sides is equal to (- 2) x 180^o.

Thus, sum of all interior angles of a pentagon = (5 - 2) x 180^o = 540^o

Being a regular pentagon, it has five equal sides with measure of each interior angle as
