The pairs of consecutive angles are supplementary. Consecutive angles share the same side (included side).
4) Congruent
Second Part:
1.) Opposite sides measurement were both 7 inch, and both 9 inch.
Let's say, in parallelogram ABCD, the opposite sides are:
2.) A parallelogram which has 130° and 50° angles.
130° + 50° = 180° (Supplementary angles total measure is 180°)
