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

  • A. 45
  • B. 55
  • C. 60
  • D. 65

Step-by-step solution

For a regular polygon with n sides, interior angle = (n-2)*180/n. The smallest number of sides is 3 (triangle), giving interior angle = (3-2)*180/3 = 60 degrees. Other options (45, 55, 65) do not correspond to integer n.
