      Mostly just writing proofs, right? I took a geometry course in grad school that taught the subject ab initio, so we were given like three axioms and then proceeded to prove the rest, using our previous proofs along the way. At the parallel line postulate the professor chose the euclidean route, but that was toward the end of the semester.
