a. Yes, hence the name parallelogram. If opposite sides weren't congruent, at least one pair of sides wouldn't be parallel.
b. Yes, two sides perpendicular (right angle) to a 3rd side are parallel to each other. A rectangle is a parallelogram with a right angle.
c. Yes, a rhombus is a parallelogram with equal sides.
d. Yes, a square is a rhombus with right angles.
e. 1 pair is parallel, but it's not confirmed to be congruent, otherwise it would be a parallelogram.
