270 SECTION 46. HYPERBOLIC GEOMETRYSuppose that F ≠ A (RAA). Then AB ‖ F G by the alternate interiorangles theorem. This means that B ≠ G (otherwise AB would intersectF G which is not possible for parallel segments).Hence □ABGF is a rectangle, which is not possible in hyperbolic geometry.Hence the RAA hypothesis is false. Hence F = A and thus B = G. Thismeans that□ABCD ∼ = □A ′ B ′ C ′ D ′« CC BY-NC-ND 3.0. Revised: 18 Nov 2012
Section 47Perpendicular Lines inHyperbolic <strong>Geometry</strong>In Euclidean geometry, if two lines l and m are parallel, and if for any pointP ∈ l we have d(P, m) = D then for every point Q ∈ l, d(Q, m) = D. Inother words, parallel lines are a “fixed distance” apart. Contrary to ourusual intuitive feeling for what parallelism means, this result is not true inhyperbolic geometry; in fact, there are at most two such points on l thatare the same distance from m!Theorem 47.1 If l is a line, P ∉ l is a point, and m is a line such thatP ∈ m, then there exists at most one point Q ∈ m, Q ≠ P , such thatd(Q, l) = d(P, l).Figure 47.1: In hyperbolic geometry, parallel lines are not a fixed distanceapart; there are at most two points on any given line that are the samedistance from any other (distinct) line.271
