3 FQ 1 of 2 What are the postulates that are used for determining congruency when using parallel lines? Postulate 3.1, 3.4, Key Concepts: Thm’s 3.1-3.3 Go over in lecture: Sect. 3.2 pg 136 # 1, 3, 4, 5-12 Exit Ticket:, m  12. What is your reasoning?

4 Geometry Date: 9/28/2011 Section 3.2 Obj: Use properties of || lines to determine   ’s & determine their  measures. Projects Due: 9/29 Chapter 2 Test Thurs. 9/29 Parking Lot pg. 104 #20, 21, 22, 23 Today is Make-up Wednesday. Missing assignments and tests must be made up today. McMillan you will take your 5 week test today after school. Bell Ringer: None HW Requests: pg 136 #15- 33 odds, 32 In Class: Complete 3.2 Crook Problems /Review sheet Chapter 2 Review Sheet HW: Study for Test Mon. Tutoring Harton/No calculator sharing

5 FQ 2 of 2 What are auxiliary lines and when do we use them? Many proofs involve lines, rays, or segments that do not appear in the original diagram. These additions to the diagram are auxiliary lines. Most auxiliary lines connect 2 pts. already in the diagram. From the figure: Drawing a line through pt. H we create angles that allow us to use our postulates and theorems to find angle measures. See Ex. 2 GP pg. 136 #11-13
