Vertical angles are not always complementary. In some cases, they will congruent and supplementary which makes them add up to 180 degrees.
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
supplementary angles are equal to 180 degrees. so two congruent(same) angles would be 90 degrees!
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 that are congruent and supplementary must be right angles.
Vertical angles are not always complementary. In some cases, they will congruent and supplementary which makes them add up to 180 degrees.
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.
They are supplementary
yes
No, right angles are 90 degrees, supplementary and vertical angles are 180 degrees.
yes they are because they meet to form at a right angle
congruent
