Geometry - Learning to Identify Multiple Examples of Consecutive Interior Angles

The video tutorial explains the concept of consecutive angles, both exterior and interior. It discusses how consecutive exterior angles are outside two lines and introduces the idea of linear pairs. The focus then shifts to consecutive interior angles, which are on the inside and next to each other. The tutorial highlights that when consecutive interior angles are supplementary, they add up to 180 degrees, indicating parallel lines. This relationship is crucial for understanding geometric proofs and properties of parallel lines.

What are consecutive angles?
