What angle pair relationships have we already investigated? Describe the relationship each angle pair has. • Vertical Angles • Complementary Angles • Supplementary Angles • Linear Pairs Yesterday, you were introduced to angle pair relationships that are created when two lines are cut by a transversal: • • • • • Corresponding Angles Alternate Interior Angles Alternate Exterior Angles Same-side Interior Angles Same-side Exterior Angles Challenge 3.1 Today, we are going to investigate those angle pair relationships when the two lines cut by the transversal are PARALLEL. Complete GSP Investigation Worksheet Practice Problems: Extra Practice Problems: https://www.khanacademy.org/math/geometry/parallel-and-perpendicular-lines/ang_intro/e/parallel_lines_2 How can we create more challenging problems involving angle pair relationships? • Incorporate systems of equations • Incorporate quadratic equations • Add more lines • Create and answer always, sometimes, never questions • PROOFS! Challenge Problems:
