Using Consecutive Interior Angles to Find Unknown Angle Measures

This video tutorial teaches how to solve for unknown angle measures using consecutive interior angles. It begins with a review of supplementary angles and addresses common mistakes in identifying consecutive interior angles. The tutorial explains the relationships between intersecting lines, vertical angles, and supplementary angles. A practical example involving street intersections is used to demonstrate the application of these concepts, showing how to calculate an unknown angle using the properties of consecutive interior angles.
