We worked through an entry task calculation today dealing with parallel lines before going over our homework together. We then reviewed three different parallel line proofs before getting started on the chapter 3 quiz review sheet. The chapter 3 quiz is on Monday, Oct. 19. The answers to the review sheet will be posted on this blog later in the weekend.
