Yes.
Not unless the parallelogram is a rectangle. In every parallelogram, consecutive angles are supplementary.
Perpendicular bisector lines intersect at right angles
Consecutive angles in a parallelogram are supplementary.
Consecutive angles of a parallelogram are supplementary.
In a parallelogram consecutive angles are always supplementary. This means they equal 180.
Then it's consecutive angles are supplementary.

Supplementary.
No.
All angles of a parallelogram are not necessarily congruent. A parallelogram means that the opposite sides run in straight lines that don't intersect. An example is a rectangle or square. Length of sides DO NOT determine if opposite angles are congruent. As long as opposite sides do not intersect each other at any point (if you continue to draw the lines), then the angles diagonal from each other are the same.
The question does not really make sense. Once might ask, "Are consecutive angles in a parallelogram complementary?" in which case the answer is no. Complementary angles are angles which add up to 90 degrees. Consecutive angles are angles next to each other (or follow each other). In a parallelogram, consecutive angles are supplementary (add to 180 degrees). In a parallelogram, opposite angles are equal. You could have a parallelogram where two angles are 45 degree (and thus complementary) and then the other two angles would be 135 degrees.
