Basically, given a convex polygon, we can form a linear pair -- a pair of supplementary angles , at each vertex.

WebTheorem: The sum of the angles in any convex polygon with n vertices is (n – 2) · 180°.Proof: By induction. Let P(n) be “all convex polygons with n vertices have angles that sum to (n – 2) · 180°.”We will prove P(n) holds for all n ∈ ℕ where n ≥ 3. As a base case, we prove P(3): the sum of the angles in any convex polygon with three vertices is 180°. WebWhat is the sum of the measures of the exterior angles of a convex polygon with n sides? We can find a formula for the sum of exterior angles using the sum of the measures of interior angles for a convex polygon with n s ides.
