How To Write a Proof - Proving Parallel Lines

The video tutorial explains how to set up a two-column proof to demonstrate angle congruence and prove parallel lines. It covers angle relationships, including alternate exterior and vertical angles, and applies the transitive property to establish congruence. The tutorial concludes by using corresponding angles to prove that lines are parallel.

What conclusion can be drawn if angle one is equal to angle two and angle two is equal to angle three?

Explain the transitive property in the context of angles.

What does it mean if corresponding angles are equal in measure?
