We continued on with coordinate geometry today by working through the midpoint formula. We had addressed this earlier in the year, but we reviewed the concept and added some more content now that we have more information to use. We went through several examples of finding midpoints from two points, finding endpoints when given the midpoint and the other endpoint, and using the midpoint concept to proved that the diagonals of a parallelogram bisect. The students then got started on their homework.
Assignment: section 13-5; page 545 CE #1-5, 9, 10
