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.
They can be but not always because supplementary angles add up to 180 degrees.
Give us a break! -- A 3° angle is congruent to another 3° angle, but their sum is only 6° , not 180°. -- Congruent angles are always equal, but supplementary angles don't have to be equal.
Angles that are congruent and supplementary must be right angles.

Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.

Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
They are congruent angles
They are supplementary

Not unless the parallelogram is a rectangle. In every parallelogram, consecutive angles are supplementary.
