Pairs of Angles

The video tutorial introduces intersecting lines and the point of intersection. It explains how intersecting lines form different types of angles, focusing on adjacent angles, linear pairs, and vertically opposite angles. Adjacent angles share a common arm and vertex, while linear pairs are adjacent and supplementary, summing to 180 degrees. Vertically opposite angles are equal and formed by intersecting lines in an 'X' shape. The tutorial provides examples and exercises to identify these angles in various figures.

What is the relationship between the measures of angles that form a linear pair?

How do you determine if two angles are vertically opposite?

Can you find the measure of angle POQ if angle POT is given? Explain the process.
