Are vertical angles always complementary?
Vertical angles are not always complementary. In some cases, they will congruent and supplementary which makes them add up to 180 degrees.
What is a counter example for the statement congruent angles are always vertical angles?
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.
What two angles are congruent and supplementary to each other?
supplementary angles are equal to 180 degrees. so two congruent(same) angles would be 90 degrees!
Uses of parallel lines cut by a transversal?
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.
What angles are always congruent?
vertical angles
Are vertical angles supplementary adjacent congruent or similar?

what-Helena was asked to prove that any pair of vertical angles is congruent. She was provided a diagram with several pairs of vertical angles.?

Angles that are congruent and supplementary must be?
Angles that are congruent and supplementary must be right angles.
Are vertical angles always complementary?
Vertical angles are not always complementary. In some cases, they will congruent and supplementary which makes them add up to 180 degrees.
Are corresponding angles congruent or supplementary?
They are congruent angles
Can a pair of angles be supplementary and congruent?
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.
Are linear pair angles congruent or supplementary?
They are supplementary
Are vertical angles congruent?
yes
Are vertical and supplementary right angles?
No, right angles are 90 degrees, supplementary and vertical angles are 180 degrees.
If two angles are vertical angles then they are congruent?
yes they are because they meet to form at a right angle
What are the nonadjacent angles in a parallelogram. Supplementary or congruent?
congruent
What is a counter example for the statement congruent angles are always vertical angles?
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.
