Remote Exterior Angles

What is the Exterior Angle Theorem?

• The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the measure of its adjacent interior angle.

• The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the measure of its opposite interior angle.

• The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of its two remote interior angles.

• The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the difference between the measures of its two remote interior angles.
