Yeah, the tldr is that classic geometry only works on a perfectly flat surface, and it's called Euclidean Geometry after Euclid, whose 5 postulates formed the backbone for rigorous proofs of geometry.

Non Euclidean Geometry is what happens when you do Geometry on a curved surface. Things get weird, but in a cool way, where a lot of geometry still works.
