In the figure below, angle with arc1 and angle with arc2 are adjacent angles:

Line AB is shown. Point C lies between points A and B and a ray extends from point C. Angle 1 is created by the ray and segment AC while angle 2 is created by the ray and segment CB.

Write an indirect proof proving that the sum of angle with arc1 and angle with arc2 is 180°.
