<font face="Times New Roman" size="+2">


Construct segment AC.  AC is a transversal for both sets of given parallel lines.  Using the Opposite Interior Angles theorem, angle DAC congruent to angle ACB and angle BAC congruent to angle ACD.  Then since AC = AC by reflexive equality, the two desired triangles are congruent by ASA.
