Web100 CHAPTER 9. POINCARE’S DISK MODEL FOR HYPERBOLIC GEOMETRY´ How can we visualize this? Surely it cannot be by just looking at the Euclidean plane in a slightly different way. We need a model with which we could study the hyperbolic plane. If it is to be a Euclidean object that we use to study the hyperbolic plane, H 2, then we Webhyperbolic geometry the Euclidean parallel postulate does not hold. In fact, given a line in a plane and a point not on the line, we have in nitely many parallels to the line through …
