Geometry; 9/7

We spent the first part of today reviewing the different vocab words we have learned to draw with a quick drawing quiz.  We then did one more distance and midpoint calculation together before getting started on the review sheet.  The bulk of the period was spent working on this in preparation for tomorrow's quiz.  Answers to the review sheet will be posted later on this afternoon.
