Lectures: MW 3:25–4:40 PM , Harkness 115

We will use the book The Geometry of Surfaces by John Stillwell as our main text for class. Supplementary resources will be posted as necessary as the semester progresses.

Course Description

We will begin with an overview of classical Euclidean Geometry and the context in which it arose, as well as its relationship to modern foundations mathematics. From there, we will take a more modern approach to geometry.

The course schedule will be used to record our progress.

Exams and Grading

There will be two midterm exams and no final. Both midterms will be held in class:

First Midterm
Wednesday 3/1
Second Midterm
In class, TBD

Your grade for the course will be based on your performance on exams and Homework.

  • Homework 30 %
  • Two Midterm Exams - 35 % each

You will NOT be permitted calculators or other electronic devices (smart phones, smart watches, etc) on any exams. You will NOT be permitted books, notes, or “cheat sheets” on any exams.

The following is a rough indication of how your course grade will be assigned and exact grade cutoffs will be determined at the end of the semester:

> 90% will guarantee at least an A-
> 80% will guarantee at least a B-
> 70% will guarantee at least a C-
> 60% will guarantee at least a D-
< 60% potentially failing

Incomplete “I” grades are almost never given. The only justification is a documented serious medical problem or a genuine personal/family emergency. Falling behind in this course or problems with workload on other courses are not acceptable reasons.


Homework will be assigned on Mondays and due the Wednesday of the next week by 3:25 PM. No late homework will be accepted. Your lowest homework score will be dropped. Homework assignments will be announced in class and on Blackboard.
