2.6 Special Angles on Parallel Lines Investigation: Use the ruler to draw two lines that are not parallel. Then draw a line that intersects them both (a transversal). Measure all the angles and write down the angle measures. Do you see any relationships?

2.6 Special Angles and Parallel Lines continued… Now draw a pair of parallel lines. Use the top and bottom of your ruler. Then draw a transversal. Notice any special angle relationships.

C-4 Converse of the Parallel Lines Conjecture If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles and congruent alternate exterior angles, the lines are ___________.

Directions for Quiz Work silently on your quiz. When you are finished flip your quiz over in front of you and work on the homework. The homework is pg 131 to 133 #1 – 10 and then #14 – 16 all the problems. Notebook check starts next class. You need to have all 8 conjectures (which include the slope formula) and all 8 notes with warm-ups starting with Ch. 1 Review and ending with Algebra Review #2. 10 pts/notes(including warm-up) = 80pts 2pts/conjecture 2x 8 = 16 pts
