... postulate). Namely, if AB is the segment perpendicular to l, where B lies in l, then the line passing through A and perpendicular to AB does not intersect l. Thus, in hyperbolic geometry, there are at least two lines through A not intersecting the line l. Then it follows that there are infinitely ma ...
