In the applet below, an

**exterior angle of a triangle**is shown. The**pink angle**and**green angle**are referred to as*remote interior angles*with respect to this**exterior angle**. What can you conclude about the measure of an exterior angle of a triangle with respect to its*2 remote interior angles?*What other theorem is readily made obvious here?
