Chapter 4 review

This is a verbal review that I would do with my students.  Chapter 4 is about reflections and how they are used in geometry, and how they are used in the real world (not a mirror).  I have tried 3 times to get Audioboo to save my recording and all three have failed.  I even tried the non flash set-up, what ever that is.  i will be posting the the no problems just answers part of BB.
