2.4 Vertical Angles

Vertical Angles: Two angles are vertical if they are not adjacent and their sides are formed by two intersecting lines

Linear Pair: Two adjacent angles are a linear pair if their non-common sides are on the same line (the two outside rays form a straight line)

Linear Pair Postulate: If two angles form a linear pair, then they are supplementary

Vertical Angles Theorem: Vertical angles are congruent
