Polygons can have any number of sides and angles, but the sides can never be curved. The sum of the exterior angles of any convex polygon is 360°. The sum of interior angles in a triangle is 180°.

Now we will learn how to find the find the sum of interior angles of different polygons using the formula.

A decagon has 10 sides, so method 1: Find the exterior angle sums, one exterior angle at each vertex, of aconvex nonagon. Interior angles are those formed by the sides of a polygon that are on the inside of the shape. The word comes from the greek words for ten (deka) and for angle or corner (gonia).
