I have been trying to prove that "rectangles do not exist" in hyperbolic geometry.
So far I have come up with this but it is incomplete and seems to prove rectangles exist. Please help.
draw ?AB to line b and then draw a line c through A ? to AB. Then we can draw D as any other point on line b drawing the ? a to b going through D. C is at the bottom of the ? to a through A. Since AC and line b are ? they do not cross each at any point.
