Angle Theorem Worksheet - The triangle exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of the two opposite interior angles. You can choose a single variable or an algebraic expression for the unknown angle. There is one worksheet on each theorem and one worksheet on both theorems. ∠d = ∠a + ∠b.
