I was out on Friday and gave Andrew a review to do with the substitute. Andrew had some difficulty recalling the formulas needed to do the problems. So we spent the day looking back through the previous content and rewriting the formulas we need. We worked out problems that had us computing the interior and exterior angles of regular polygons. Then we worked out problems with various quadrilateral types. We discussed the relationships with the diagonals, whether they were congruent or bisected. We will finish the review tomorrow.
