Answer:

Statement:                         Reason:

-----------------------------------------------------------------------------------------------------------

1. line DA = line CB                   1. It is a parallelogram (two sets of parallel lines)

  line DC = line AB

-----------------------------------------------------------------------------------------------------------

2. m<b + m<c = 180 degrees    2. Same side Interior Angles Theorem

   m<d + m<a = 180 degrees.      (If two parallel lines are cut by a transversal,

                                                      then the same side interior angles are

                                                      supplementary.)
