7.1 ADJACENT AND VERTICAL ANGLES

ADJACENT ANGLES

• Two angles are adjacent angles when they share a common side and have the same vertex.

VERTICAL ANGLES

• Two angles are vertical angles when they are opposite angles formed by the intersection of two lines.

• Vertical angles are congruent angles, meaning they have the same measure.
