We continued our work with coordinate geometry today by taking a look at how midpoints are used to prove various facts about figures that are graphed. We went over how to determine the midpoint of a segment, and then to use this midpoint formula to prove that diagonals bisect in a variety of figures. We went over 2-3 examples of this together before getting started on the assignment.
Assignment: circle worksheet + section 13-5; page 545-546; WE #1-12 all, 15, 18
