Sometimes they are, sometimes they are not.

Ajt
Angles that are congruent and supplementary must be right angles.
Adjacent angles in a parallelogram are supplementary.
No. In a parallelogram, opposite angles are congruent.
Sometimes they are, sometimes they are not.
Yes, opposite angles of a parallelogram are congruent.
Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.
They are congruent angles
No, a pair of angles that are supplementary will always have a sum of 180 degrees, while a pair of angles that are congruent will have the same measure. Therefore, it is not possible for a pair of angles to be both supplementary and congruent.
Consecutive angles are supplementary Diagonals bisect each other Opposite angles are congruent Opposite sides are parallel
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
