This course is the second part of a series that starts with Math 444. We will be winding our way through the rest of the textbook (Chapter 8 and further), covering select topics that will span pretty much all chapters.

Textbook

We're using John M. Lee's Axiomatic Geometry, referred to below as AG. The textbook is absolutely necessary, both for the reading and in order to do the assignments.

You'll also need access to Book I of Euclid's Elements, available electronically here.
Reading

It's essential that you do the reading. I won't have time to go over every relevant example in class, and you'll need a good grasp of the material in order to do the homework. In fact, I encourage you to regard the reading as part of your homework.

Each reading assignment will be paired with a homework assignment so that they're numbered identically in the two tables. Unless I say otherwise, 'Chapter X' refers to the textbook, AG.

Homework

I will list the problems from AG, as numbered there. The numerical part indicates the chapter, so say problem 1A is at the end of chapter 1 in AG, and so on.

There will be homework due every class, and you have to turn it in at the beginning, before the lecture. No late homework for any reason, but I will drop the two lowest scores.

Because of time constraints your TA will grade a couple of problems (tops) for correctness and the rest for completeness. I won't be telling you in advance which problems are graded for correctness though..

Quizzes

These might happen on any lecture day at any time during class, but I'll let you know at least a day ahead of time. I am not sure how many we'll have, but probably at least one each week, and I'll bring them back with me on the following lecture day.

They'll be quick 10-minute affairs having to do mostly with matters of logic, short proofs, definitions, or other such things that you can answer quickly. Each quiz will probably consist of a single question / problem.

There are no make up quizzes, but I'll drop the lowest one.

Answers to Quiz 1.

Answers to Quiz 2.

Solution for Quiz 3.

Final

It's going to be in class, on the last day of the term, at the usual time:

Grading
As mentioned above, we'll drop the two lowest homework scores as well as the lowest quiz.
Overloading

"Overloading" means allowing more students in class than the limit (which in our case is 35). Because 35 is also our room limit, there will be no overloading.
Disability Resources

If you need special accommodations please go to DRS (Disability Resources for Students) for more information. You should meet with a DRS counselor and get a letter attesting your need for academic accomodations. Once you have such a letter, please see me so that we can arrange for those.
If you have any questions, don't hesitate to email me.
