We spent time today going over the first review sheet from chapter 3 before going into today's lesson. We went over one more parallel line proof together, as well as reviewing a series of angle diagrams that prove parallel lines. The students then got started on their second review sheet in preparation for the chapter 3 test on Monday.
The answers to the 2nd review sheet will appear on this blog later in the weekend.
Assignment: Chapter 3 Review Sheet #2
