  1. Warm up: Classify the pair of numbered angles 1. 1 5 Corresponding Angles 2 2. Alternate exterior angles 7 3. 4 Alternate interior angles 5

  2. Proving Theorems: 3.2

  3. Corresponding Angles Postulate • If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent. 1 2 ~ <1 = <2

  4. Alternate Interior Angles Theorem p Given  p || q Prove  <1 = <2 1 2 q 3 1. Given 2. Corresponding Angles 3. Vertical Angles 4. Transitive Property

  5. Alternate Exterior Angles Theorem 1 p Given  p || q Prove  <1 = <2 3 q 2 1. Given 2. Corresponding Angles 3. Vertical Angles 4. Transitive Property

  6. Consecutive Interior Angles Theorem p 1 Given  p || q Prove  <1 and <2 are supplementary 2 3 q 1. Given 2. Alternate Interior Angles 3. Linear Pair 4. Substitution Property

  7. ClassWork • Get out your books. • Open up to page 160 • Complete problem #42 We will go over this question! T-sip rules even Mrs. Miller knows it!!!! 

  8. Homework • Pg 157/1-3,7,8,13,15,18,19,21-37, 39-41,43,47,50,52
