If I know the number of sides of a regular polynomial(10), how do I find the exterior and interior angles?

  1. Do you mean polygon? If so, this is how you figure out both:

    Interior (sum):
    (n-2)180
    (10-2)180
    (8)180
    1440
    Then divide this number by the number of sides.
    1440/10=144.

    Exterior (sum):
    Since the exterior angle sum of any regular polygon is 360, divide this number by the number of sides.
    360/10=36.


    I hope this works for you!
