  2. 3-2 Properties of Parallel Lines

  3. Postulate • If two parallel lines are cut by a transversal, then corresponding angles are congruent • What 4 pairs are congruent? • Note the arrows on the lines: means they are parallel. 1 2 3 4 5 6 7 8

  4. Theorem • If two parallel lines are cut by a transversal, then alternate interior angles are congruent • What 2 pairs of angles are congruent? 1 2 3 4 5 6 7 8

  5. Theorem • If two parallel lines are cut by a transversal, then same-side interior angles are supplements. • SSI starts with “S” and is the only one that is SUPPS!! • What 2 pairs are supps? 1 2 3 4 5 6 7 8

  6. Theorem • If a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other line as well.

  7. Example • Find x, y, and z. 110 x 2z 2y

  8. TOO • Find x, y, and z. z y 2x 40

  9. Homework • Page 80-82 #1-16, 20, 21 • #20 and #21 are 4 Step Proofs (See whiteboard) • See overhead for help with some!! • Flash Cards • 3 Theorems and a Postulate • Corr angles • SSI angles • Alt. Int angles • If perp. to one line then perp. to another • Draw a picture on the flashcards!!
