Anyone else struggle with geometry?

10. That's what it's supposed to be these days. For the most part.

Its use by geometers is assumed, but for most of us it's how to start with a set of axioms and deduce a fairly large set of internally self-consistent rules. Training for rigorous, logical thinking and upper levels of math.

Seldom taught that way. The schools I've seen tend to teach it as a series of precepts to be memorized. Thus it's the equivalent of buying an AKC-certified prize-winning stud, and when you take him to the vet for his initial check up stipulating that he be neutered.
