Office Hours are on Mondays, 5:00 p.m. - 7:00 p.m.  If you are coming after 5:30 p.m., please let me know so that I know to wait for you and do not leave early.

Here is a practice exam for midterm 1, which was used by me in this class in 2008.  The best way to study for the exam is to go over old homework problems, other book problems in the same sections, and the problems in the above exam.   I also expect you to be able to prove the major theorems of the course if asked.  So know the proofs of:

The Rule of Pythagorus
The Star Trek Lemma
Power of the Point
Medians intersect at a point
Angle Bisectors intersect at a point
Perpendicular Bisectors intersect at a point
Altitudes intersect at a point
Law of Sines
Law of Cosines
The Euler Line
The Nine Point Circle
The Simson Line
Menelaus's Theorem
Ceva's Theorem

Expect 3 of the problems to be proving a selection of the above theorems, and the other 3 problems or so to be from the homework and related problems.
