Honors Geometry; 2/2

We went over our first review sheet today for the chapter 8 test.  This was a longer assignment and the students had several questions to get answered.  We then spent a little time reviewing special right triangles together before getting started on the second review sheet.  The answers to this 2nd review sheet will be posted on this site later this afternoon.  Both review sheets will be turned in tomorrow before we take the chapter 8 test.
