2. Angle A is congruent to Angle D; Angle C is congruent to Angle B 3. EA = ED  Definition of Midpoint 4. The triangles are congruent by AAS Theorem

Directrix (directrix):

Reason 2 is "If 2 parallell lines are cut by a transversal, then alternate interior angles are conguent."

OpenStudy (anonymous):

Angle A is congruent to Angle D, Angle C is congruent to Angle B because alternate interior angles of parallel lines are congruent. EA = ED because this is the definition of midpoint. So by AAS, triangle AEC is congruent to triangle DEB.
