Exterior Angle Theorem. For a triangle: The exterior angle d equals the angles a plus b.; The exterior angle d is greater than angle a, or angle b. remote interior. This gives us the ability to predict how long a third side of a triangle could be, given the lengths of the other two sides. Try moving the points below: When the three sides are a, b and c, we can write: a < b + c. b < a + c. c < a + b. geogebra theorem observations. If D is any point on the opposite ray of AC, then DAB is an exterior angle of the triangle ABC at A. The exterior angle theorem states that the sum total of all the remote interior angles of the triangle is equal to the non-adjacent exterior angle of that triangle.
