The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent.
The exterior angle theorem tells us that the measure of angle D is equal to the sum of angles A and B. In formula form: m<D = m<A + m<B Think back to our common fact that a straight line is equal to 180 degrees.
