Geometry Tuesday 11-11-14 Warm-ups – Complete Slide below – Check in and discuss A#3.1 Discussion/Notes/Guided Practice – Section 3.2 Angles and Parallel Lines Assignment: – A#3.2 Page 136 #14-25, 32, 34, 36 Today, you will be able to: Use properties of parallel lines to determine congruent angles Use algebra to find angle measures Success Criteria: Q&A Exploration Activity Foldable Guided Practice Homework Warm ups – Angle exploration Cut out one set of angles (1 – 8). Use these angles to determine special angle relationships with the other angles. List any special relationships you find: Compare with your partner. 3-2 Parallel Lines and the Angles Formed Corresponding Angles Postulate: 2 1 3 4 6 5 7 8 Alternate Interior Angles Theorem: Alternate Exterior Angles Theorem: 2 a 1 3 4 b 6 5 7 8 Consecutive Interior Angles Theorem: 2 a 3 4 b Perpendicular Transversal Theorem: 1 6 5 7 8 Proof of Alternate Interior Angles Theorem 2 a 1 3 4 b 6 5 7 8 Proof of Consecutive Interior Angles Theorem 2 a 1 3 4 b 6 5 7 8 Example #1 Example #2 Example #3 Assignment #3.2 Page 136 #14-25, 32, 34, 36
