We teach three undergraduate geometry courses: one for future high school teachers which basically goes over high school geometry, hopefully with a little more perspective; a course called modern geometries, which is basically hyperbolic geometry through the Poincare halfplane, and whose audience is again largely future high school teachers; and differential geometry, whose audience is largely math majors and majors in fields close to math (e.g. physics). Of course much of calculus is also concerned with geometry -- area, arclength, surfaces, curvature, and so on.
