Were you a high GPA student?

May I ask what topics are covered in the geometry book?

I believe, essentially: 1) a history of Euclid's elements, including notions of constructibility, treated comparatively alongside Hilbert's axiomatization of geometry, 2) a discussion of the history of Euclid's fifth (parallel) postulate, along with various attempts to prove it, 3) the revolutionary work of Riemann and others, and why it provided the framework for non-Euclidean geometries, 4) the discovery/formulation of non-Euclidean geometries, and the accompanying proof of their consistency, and 5) specific topics in hyperbolic geometry.
