4.3 HW Exterior Angle Theorem - IAG

Front

What is the Exterior Angle Theorem?

Back

The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

Front

If angle A and angle B are interior angles of a triangle, what is the relationship between them and the exterior angle C?

Back

Front

How do you find the measure of an exterior angle if you know the measures of the two non-adjacent interior angles?

Back

Add the measures of the two non-adjacent interior angles together.

Front

What is the relationship between the exterior angle and the adjacent interior angle?

Back

The exterior angle is equal to the sum of the two opposite interior angles, not the adjacent one.
