Which angle has the greater measure? A. angle A B. angle E C. angle C D. The angles are congruent
angle A because exterior angles are larger than the interior angles
@nikato, you have the correct answer but the wrong reason. Look in figure below. Exterior angle 1 is larger than interior angle 2, so your statement is oncorrect. |dw:1383022437676:dw|

There is a theorem that states: In a triangle the measure of an exterior angle is equal to the sum of its two remote interior angles.
no, its an exterior angle is greater than each of its remote interior angle
That's better. In this triangle, angle A is an exterior angle and angles E and C are its remote interior angles. Since m<A = m<C + m<E, that means m<A must be greater than m<C or m<E.
