Final answer:
Angle pairs in Mathematics are formed by intersecting lines. Vertical angles are congruent and adjacent angles form linear pairs. Use these properties and relationships to find missing angle measures.
Step-by-step explanation:
Angle pairs in Mathematics are formed by intersecting lines. When two lines intersect, they create four angles. The angles that are opposite each other and not adjacent are called vertical angles, and they are congruent. The angles that are adjacent and share a common side are called adjacent angles. If two adjacent angles add up to 180 degrees, then they are called a linear pair of angles.
For example, if angle P and angle Q are adjacent angles and they add up to 180 degrees, then they form a linear pair of angles. This means that angle P and angle Q are supplementary angles.
To solve problems involving angle pairs, you can use these properties and relationships to find missing angle measures.
