In a triangle, what is the relationship between the measure of an exterior angle and the measures of the two remote interior angles?

• The measure of an exterior angle is equal to the sum of the measures of the two remote interior angles.

• The measure of an exterior angle is equal to the difference between the measures of the two remote interior angles.

• The measure of an exterior angle is equal to the product of the measures of the two remote interior angles.

• The measure of an exterior angle is equal to the average of the measures of the two remote interior angles.

In a triangle, can the measure of an exterior angle be greater than the measure of either of the two remote interior angles? Why or why not?

• Yes, because the exterior angle can be any measure

• Yes, because the exterior angle can be greater than both interior angles

• No, because the exterior angle is always smaller than both interior angles

• No
