We went over the chapter 4 quiz to start the period today before getting started with the lesson. Today's focus was on how to use the isosceles triangle theorem in working through triangle proofs. We did a couple of proofs together to show the different aspects of what the theorem is, and then we went through some basic calculations using isosceles triangles. The students then got started on their homework.
Assignment: section 4-4; page 137-139; WE #1-10 all, 13-17 all, 20-30 evens
