The Exterior Angle Sum Theorem states that the sum of the exterior angles of any convex polygon is (360^(circ)). If a polygon is regular with n sides, each exterior angle is equal to 360 degrees. In a regular polygon, the measure of each exterior angle can be found using two formulas: 360 ∘ n and 180 ∘ − (n – 2) 180 ∘ n (180 ∘ minus Equiangular Polygon Formula).
The sum of exterior angles of a convex polygon is equal to 360°/n, where n is the number of sides of the polygon. In the case of convex polygons, where all vertices point “outwards” away from the interior, the exterior angles are always on the outside of the polygon. The measure of an exterior angle can be calculated using the formula $180(n;-;2)^circ$.
The sum of the interior angles of a convex polygon is given as $frac(360^ circ)(n)$. The key focus of these tasks is to understand what counts as an exterior angle and the different ways this can be expressed. If a polygon is convex, then the sum of the measures of all exterior angles, one at each vertex, is always 360°.
