So my math class is Geometry and we learned theorems eleven one and theorem eleven two. Theorem eleven one is the polygon interior angle theorem which says the measure of the interior angle of a convex n-gon is (n-2) times one hundred eighty. The corollary is the measure of each interior angle of a regular n-gon is (n-2) times one hundred eighty divided by n. Basically what you do is the book gives you how many sides there are in the polygon (n) and you just substitute that number for n.

Now theorem eleven two is the polygon exterior angle theorem which says the measures of the exterior angles of a convex polygon, one angle at each vertex is three hundred sixty degrees. Its' corollary is: the measures of each exterior angle of a regular n-gon is three hundred sixty divided by n. To sum it the book gives you a number of sides (n) and you substitute that number for n. For example if the number of sides is fifteen you divide three hundred sixty by fifteen and what ever the anser is then, that's how many degrees it is.
