Geometry; 12/12

We completed our quadrilaterals chart today by filling in the properties of kites that we had worked with yesterday.  We then worked through 2 problem types for the test together before getting started on the review sheet.  The students had the last half of the period to work on the chapter 5 review.  The chapter 5 test is tomorrow.
