Geometry assignment; 10/2

We spent time in class today reviewing for the test tomorrow.  Part of the review packet we did in class and corrected at the end of the period.  The other portion of the review guide is homework.  The answers appear below to that review guide.  We won't go over the review guide tomorrow in class, so it would be a good idea to read through the study guide and check your answers before coming tomorrow.

Test on Chapter 2 is tomorrow.
