The sum is always 360 degrees. Note, though, that when the interior angle is convex, the measure of the exterior angle is negative.

Is the sum of the interior angles of a convex polygon the same as a non-convex polygon?
No. In a convex polygon the sum of the interior angles is (n-2)*180 deg where n is the number of interior angles. In a non-convex polygon this is not necessarily true.
What does a non convex polygon look like?
A non convex polygon would have an exterior angle less than 90 degrees making it look concave at that vertex.
What are characteristics of non polygons?
it has a number of faces, vertex and edges -- The angles are not all the same
What the difference between convex and non convex polygons?
In a non-convex (or concave) polygon, at least one interior angle is a reflex angle. An alternative definition is that if you take any two points inside a conves polygon, the line joining them is wholly inside the polygon.
What is the sum of the exterior angle measures of a 15-sided polygon?
The exterior angles of a REGULAR 15-gon are 204o, so the sum would be 3060o. This remains true for non-regular 15-gons as well (the exterior angle sum, not the exterior angles).
