According to the angle sum property of a Quadrilateral, the sum of all the four interior angles is 360 degrees. Proof: In the quadrilateral ABCD, ?ABC, ?BCD, ?CDA, and ?DAB are the internal angles. AC is a diagonal; AC divides the.
Theorem for Exterior Angles Sum of a Polygon. If we observe a convex polygon, then the sum of the exterior angle present at each vertex will be 360°. Following Theorem will explain the exterior angle sum of a polygon: Proof. Let us consider a polygon which has n number of sides. The sum of the exterior angles .
