they are congruent: exactly equal
Are vertical angles congruent or supplementary angles?
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
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 is the difference between vertical angles and congruent angles?
not all congruent angles are vertical angles. Vertical angles must share a vertex.
