Proofs for angles
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°. WebStatement #2: This statement is used to show that congruent angles are equal in measure. Statement #3: In an earlier unit, we examined angle addition. When two angles share a …
