the union of two convex sets need not be a convex set.
In general, you cannot. All that you can say for a polygon with n sides is that the angles sum to (n-2)*pi radians - or (n-2)*180 degrees. This is true for cocave polygons as well as convex ones. For a concave polygon, if you wish to measure a reflex angle using a protractor, measure the outside angle and subtract that from 2*pi radians (360 degrees).
