Ever want to read about Euclidean geometry from the man himself? Thanks to a Facebook friend, I’ve learned that Euclid’s Elements is free online. Obviously out of copyright and all. Being Euclid. Though it’s had to be translated into English and such. Regardless, it’s available online. For free.
Fun with geometry! One of my favorite maths. Anyone have a favorite theorem or postulate? I’m partial to proofs. They’re like fun logic puzzles with a purpose!
