MAT 360 . Lecture 10 Hyperbolic Geometry. What is the negation of Hilbert’s Axiom?. There exists a line l and a point P not on l such that there are at least two parallels to l through p. Hyperbolic axiom.
all triangles are congruentAll triangles have angles 22.5 degrees, 60 degrees, and 90 degrees.
we “see” in this picture is not the one given by Theorem 4.3
Where in the proof are we using the hyperbolic axiom?
