90 degrees is the angle
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
If all adjacent angles are congruent, it can only be a rectangle (or square).
Two adjacent angles are considered supplementary angles. They aggregate and make an angle that measures 180 degrees.
Rectangles have congruent adjacent angles.
supplementary angles are equal to 180 degrees. so two congruent(same) angles would be 90 degrees!
Congruent *apex
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.
Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
Angles that are congruent and supplementary must be right angles.

90 degrees each
Adjacent angles in a parallelogram are supplementary.
Yes, adjacent angles are supplementary; however, opposite angles are not.
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.
They are congruent angles
The adjacent Supplementary angles are the sum of 2 angles that make 180 degrees.
Supplementary angles are two angles whose measures add to 180 degrees. Adjacent angles are two angles that happen to lie next to each other, so that they combine to form a larger angle whose measure is the sum of the measures of the adjacent angles. Angles may be both adjacent and supplementary, in which case they will form a straight angle.
