Exploring Angle Relationships with Parallel Lines

Mr. Dresser introduces angle relationships and parallel lines, covering essential vocabulary such as congruent and supplementary angles. He explains how to create a flipbook for studying and delves into various angle relationships, including vertical, linear pairs, corresponding, alternate exterior, alternate interior, and consecutive interior angles. The video concludes with sample problems to reinforce the concepts.

What does it mean for two angles to be congruent?

• They add up to 180 degrees.

• They have the same size and shape.

• They are adjacent to each other.

• They form a straight line.
