Practice finding the missing angle measures;
1. Can you determine the relationship between the measure of angle ACE, an exterior angle, and the measures of the two remote angles, angle CED & angle CDE?[br][br]Explain the relationship.
2. The exterior angle of a ∆ is 68˚ & one of its remote angles is 47˚, what is the measure of its other remote angle?
21˚[br]68 – 47 = 21[br](ext angle = sum of the two remote int. angles)
3. Name another exterior angle (not the one mentioned in #1) and name its two remote interior angles.
Exterior angle: angle EDB.[br]its remote angles are: angle E & angle ECD
