           SUBTOPIC: Exterior angle and Angle sum property of a triangle






             • An exterior angle of a                                      Exterior angle
                 triangle is equal to the sum                               property of a

                 of its interior opposite

                 angles.                                                           triangle





            • The total measure of three                                        Angle sum
