Best Answer

The exterior angles of any polygon add up to 360 degrees, regards of the number of sides. I'm thinking integers >2 -- if there is a way to make a polygon with negative, fractional, irrational, imaginary sides, then maybe that doesn't add up to 360. I'm also assuming Euclidian geometry -- on a sphere, for example, it wouldn't be 360.
