The video tutorial explains how to determine the measures of angles formed by intersecting lines. It highlights that if one angle is a right angle, all angles are 90 degrees, indicating perpendicular lines. The tutorial then guides viewers on solving for unknown angles by setting up equations, emphasizing the importance of assigning variables and solving systematically.

If the measure of angle 4 is 32 degrees, what equation can be set up to find the measure of angle 5?

Measure of angle 4 * measure of angle 5 = 90 degrees

Measure of angle 4 + measure of angle 5 = 90 degrees

Measure of angle 4 - measure of angle 5 = 90 degrees
