Solutions for Test 5 are posted below.
The Final Exam will be on Thursday 1/17 at 9:00 AM. It will be comprehensive (cover the entire course), and 80% of the exam will be common across all 8 Geometry Sections: 20 Multiple Choice (40%) and 4 Proofs (40%). The remaining 20% will be specific to topics emphasized in our class, and may consist of proof and/or non-proof questions.
Test 5 will be all Multiple Choice (see the Fall 2011 Test 5) and will be held on or about Tuesday 1/15. It will cover all or most of Textbook sections 9.8 and 10.1-10.6.
Solutions and Statistics for Test 4 are posted below.

Test 4 will cover Textbook Sections 9.7 (Hy-Leg Theorem, Angle Bisector, & Incenter), 5.6 (Perpendicular Bisector & Circumcenter), 9.1 (Proving Lines Parallel), and 9.2 (Properties of Parallel Lines), as well as the the other Triangle Centers discussed in class. You will also be expected to be proficient in the material covered by Test 3.
Blank copies of the Fall 2011 Test 4 can be downloaded here. Problem 6 is not relevant for your Test 4 and Problem 7 was on your Test 3.

There will be a very short 10-point "extra credit" Quiz covering the assigned reading/studying of textbook Section 4.1 on Tuesday 11/20. The Quiz points will be added directly to your Test point total before averaging but after dropping your lowest Test score, so effectively they will be added to your second lowest Test score.
Test 2 will cover Textbook Sections 1.1-1.6, 3.1-3.8, & 4.2, as well as any material covered in class that is not in the book.
Period 3 Test Date Fri 11/9

If you received a score of 55 or below on Test 1, you are required to make an appointment with me to discuss your test on or before 10/26. If you received a score of 56-65, it is strongly recommended that you make such an appointment.
The Algebra II Placement Test will be given at the below dates and times. If you are interested in being placed in Algebra II instead of Algebra I next semester, and you did not take the Placement Test last summer, you must take the Test on one of these two dates. If you do not take the Placement Test, you will automatically be placed in Algebra I. If you have questions, speak to anyone in the Math Department.

It is strongly suggested that you do Fall 2010 Test 1 and Fall 2011 Test 1 as practice tests. Solutions to Fall 2011 Test 1 can be found here.
Test 1 will cover all the Chapter 2 HW listed in the Homework section. This corresponds to Textbook Sections 2.1-2.7 plus all the material covered in class that is not in the Textbook - namely De Morgan's Laws, the Chain Rule, and two-column Logic Proofs.

Beginning with HW 3.1-3, solutions to all homework problems should be written-up neatly, showing appropriate and sufficient work. You should be prepared to either turn in each homework assignment, or put problems on the blackboard if asked. Therefore, make sure you include sufficient information in your written work to fully explain each problem (for example, you will need to redraw any diagrams).
