Concave Polygons and Exterior/Interior Angles

Hi Everyone,

I know that middle school/high school students learn that for any
polygon(convex or concave) with n sides, the sum of the interior angles
is 180(n-2) and that the sum of the exterior angles for a convex
polygon is always 360.

But is there any generalization for exterior angles of a convex
polygon? I've looked online and haven't been able to find any sources
that give a straight yes or no answer.

Thank you for your help.
