They are supplementary

Corresponding angles in similar figures should be the same, not supplementary.

Their corresponding angles and corresponding sides are congruent.

The answer is supplementary! :-)

Angles that are congruent and supplementary must be right 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.

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

congruent

Corresponding sides and angles are not all congruent.

Their corresponding angles and corresponding sides are congruent.

The answer is supplementary! :-)

Angles are congruent if they are equal. Corresponding angles in figures that are similar are congruent.

Give us a break! -- A 3Â° angle is congruent to another 3Â° angle, but their sum is only 6Â° , not 180Â°. -- Congruent angles are always equal, but supplementary angles don't have to be equal.

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.
