Honors Geometry; 1/4

Welcome back from break!  We had shortened periods today due to the 2-hour delay, but we were able to go through an assignment and review some key topics for tomorrow's quiz.  The students then had some time at the end of the period to work on their chapter 7 quiz review sheet.
