Honors Geometry; 3/21

We went over the homework problems today before reminding everyone about the different types of drawings involved in the quiz tomorrow.  We reviewed how to draw circles and spheres, and which drawings to recognize for the shortcuts they afford.  The students then got started on their review assignment.
