Honors Geometry; 11/15

We spent some time going over the chapter 4 review sheet to begin class.   We then went over one proof together from the proof packet to illustrate one more overlapping triangle proof.  The rest of the time the students had to work on finishing their proof packet and the 2nd review sheet for chapter 4.

Chapter 4 Test is tomorrow.
