    Hints: Based on the definition of a parallelogram is "A quadrilateral with both pairs of opposite sides parallel." (ref. http://www.mathopenref.com/parallelogram.html) you can show \(\angle ABD \cong \angle CDB\) \(\angle BAC \cong \angle DCA\) and finally \(mAB \cong mDC\) (takes a few steps). Try the above steps, and if they work, choose your answer. Note that if you use a different definition of a parallelogram, the result can be different.
