Angle Relationships and Theorems

The video tutorial explains the concept of a transversal intersecting parallel lines, leading to various angle relationships. It covers the corresponding angles postulate, which states that corresponding angles are congruent. The video also discusses vertical angles and linear pairs, highlighting their congruence and supplementary nature. It further explores alternate interior and exterior angles, proving their congruence through theorems. Lastly, it examines same side interior angles, showing they are supplementary.
