Angle DAB is an exterior angle of the triangle. Angles C and B are the [b]remote interior angles[/b] of this exterior angle. You can change the triangle by moving the vertices. Explore until you can answer the following questions. Discuss with your partner, then write your final answers (with a diagram!) in your notebook.[br][br]1) What do we mean by the [b]remote interior angles[/b] of an exterior angle?[br]2) What is the relationship between the measures of the exterior angle and its two remote interior angles?[br]3) WHY do you think they have this relationship?[br]4) Can you PROVE this relationship from our existing theorems?
