I will be teaching geometry for the first time ever this summer. I teach at a community college, and we only offer this course in the summer. (Mostly high school students take it, but it is a college course.)
I have just started to read the textbook we use: Elementary Geometry for College Students, by Alexander and Koeberlein. So far I am not impressed.
I would like to know of good textbooks others have used for such a course. Sadly, the only book I found that's OER is a photocopy.
ETA: Problems with the current textbook: It feels like a mish mash. I saw a definition that was incorrect. ("Adjacent angles have one corresponding side." Well, that would be true if one angle were inside the other, and I don't believe we call those adjacent.) I don't care for the two-column proofs, and the way they try to teach them. I don't see what the goal is when I work through this book. There are 'theorems' with no proof in sight. How do you prove things if you don't know what your starting point (the axioms) is?
My criteria for a good textbook: It will work with me to strengthen the students' visual reasoning skills. It will do a good job with construction. (I can do that on the side, though.) It will do undefined terms to axioms / postulates to proofs well. It will have a good flow / progression. It will inspire me and the students (fun and meaningful). For example, I mostly like what I see in James Tanton's book.
