What your son is learning (synthetic geometry) and what you learned (cartesian geometry) are essentially two ways of looking at the same stuff. One emphasises coordinates and one does not.
What the post is about (non-Euclidian geometry) is a rather different thing entirely. Its about doing geometry when the space you live on/in is curved (like doing geometry on the surface of the earth).
- sixdrum 3y agoThanks for the clarification. I'm taking in as many resources as I can. I'd imagine that if he goes into engineering or CS, and especially into anything having to do with 3D environments, that cartesian geometry would be more useful.
