Talk:Poincaré Plane is Abstract Geometry

I see the latest changes in this page to Axiom 2. Does this mean that the original was incorrect? As it was cited to come from a published work, then we may need to check back with that work to see what it actually says, and if it is definitely wrong, issue an errata report. --prime mover (talk) 10:07, 23 July 2017 (EDT)
