HOMEWORK-PRACTICE TEST
• Do each question WITHOUT looking at the answer…
• Check the answers online on my website!http://rachelsawyer.cmswiki.wikispaces.net/Geometry MUST USE FIREFOX OR GOOGLE CHROME (does not
work in internet explorer)• Use your notes/quizzes to figure out what you
did wrong!
• Study!!!! STUDY!!! STUDY!!!!
