12.8: Axiom h-V

( \newcommand{\kernel}{\mathrm{null}\,}\)

Finally, we need to check that the Axiom h-V holds; that is, we need to prove the following claim.

Theorem 12.8.1

Claim For any h-line and any h-point P there are at least two h-lines that pass thru P and have no points of intersection with .

Instead of Proof

Applying the main observation we can assume that P is the center of the absolute.

The remaining part of the proof can be guessed from the picture

Exercise 12.8.1

Show that in the h-plane there are 3 mutually parallel h-lines such that any pair of these three lines lies on one side of the remaining h-line.

Hint

Look at the diagram and think.
