Exploring Angle Relationships in Geometry

The video tutorial explores various angle relationships, including supplementary, vertical, corresponding, and alternate interior angles. It explains these concepts using diagrams and examples, and demonstrates how to solve puzzles by applying these angle relationships. The tutorial emphasizes understanding the properties of angles formed by parallel lines and a transversal, and how these properties can be used to solve mathematical problems.

What are supplementary angles?

• Angles that add up to 90 degrees

• Angles that add up to 180 degrees

• Angles that are adjacent

• Angles that are equal
