Geometry; 4/29

We continued working with coordinate geometry and slope today, going over how to determine if lines are parallel or perpendicular.  We went over some mental math exercises to practice this, and then looked at a couple of figures as well.  The students then got started on their assignment.

Assignment:  section 13-3;  page 536;  CE  #1-9;    page 537;  WE  #1-6, 9-11
