if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
The Congruent Supplement Theorem states that if two angles are supplementary to the same angle (or to congruent angles), then those two angles are congruent to each other. In other words, if angle A and angle B are both supplementary to angle C, then angle A is congruent to angle B. This theorem is useful in proving relationships between angles in geometric proofs.
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.
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.
Angles that are not congruent have different measures and do not represent the same degree of rotation. For example, a 30-degree angle is not congruent to a 60-degree angle because their measures differ. Additionally, angles that are complementary (summing to 90 degrees) or supplementary (summing to 180 degrees) can also be non-congruent, as they do not have equal measures.

Supplementary Congruency Theorem

Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
supplementary angles are equal to 180 degrees. so two congruent(same) angles would be 90 degrees!
Congruent angles (or equivalent angles) have the same angle measure.
Angles that are not congruent have different measures and do not represent the same degree of rotation. For example, a 30-degree angle is not congruent to a 60-degree angle because their measures differ. Additionally, angles that are complementary (summing to 90 degrees) or supplementary (summing to 180 degrees) can also be non-congruent, as they do not have equal measures.
Two angles that are congruent have the same angle measurement.
There's lots of useful things you can discover when parallel lines are cut by a transversal, most of them having to do with angle relationships. Corresponding angles are congruent, alternate interior angles are congruent, same side or consecutive interior angles are supplementary, alternate exterior angles are congruent, and vertical angles are congruent.
Angles with the same angle measure are congruent.
