What is the value of each interior angle of a regular pentagon?
Explanation
Explanation
The sum of interior angles of a polygon with n sides is (n-2) x 180 degrees. For a pentagon (n=5), this is 3 x 180 = 540 degrees. Since a regular pentagon has 5 equal angles, each interior angle is 540/5 = 108 degrees.
PRO TIP
Re-check your working by substituting the answer back into the original question.
