A regular 18-sided polygon, an octadecagon or octakaidecagon, will have interior angles that each measure 160 degrees. Use the link below to a presentation on all 'gons. It's short, cool and really easy to understand. By the way, the formula for the sum of all the interior angles of any convex polygon is (N-2) x 180 degrees, where N = the number of sides. In the 18-sided 'gon here, we plug in the 18 for the N and 18 - 2 = 16, and 16 x 180 = the sum of all the interior angles, and lastly ('cause you wondered where we were going with this), 16 x 180 divided by 18 (the 18 being the number of sides) = 16 x 10, and that equals 160 degrees. And that's where the 160 degrees above came from. Have you been convinced to use that link? Hope so!
