Would I get a proper understanding of Geometry if I read Euclid's Elements of Geometry? Rather, would I get an understanding of geometry on par or above that of which is taught in highschools?
I was kicked out of high school during 10th grade and basically had to sacrifice my geometry class, and while mathematics generally comes easily to me, I still don't know pretty much any geometry besides the basic trigonometry used in Calc and the obvious stuff like the areas and perimeters of squares/circles.
