Our topic today focused on how to write coordinate proofs using only variables. We went over 3 together and connected them to earlier work with the distance, midpoint, and slope formulas. The students then got started on their own assignment of working through a few coordinate proofs.
Assignment: section 13-9; page 562; WE 1, 2, 4, 7 + coordinate proofs worksheet #3, 5, 7
