These properties are used to show the existence of an order-preserving isomorphism between the set of all real numbers and the whole line. The chapter ends wit

SpringerBriefs in Earth SciencesA belineation is a bijection of a plane that preserves betweenness. This chapter shows that every belineation on a Pasch plane is a collineation, and explores the interactions between belineations and segments, rays, lines, sides of a line, angles, and triangles.

Basics of Learning Devotional Hindu Dance,This chapter defines point rotations and point reflections (about a point .) on a neutral plane, and derives their elementary properties to the extent possible without a parallel axiom. It ends with a classification of isometries of a neutral plane, and proof of the existence of a “square root” of a rotation.

,Schlussbetrachtung – Resümee und Ausblick,This brief chapter shows that on a Euclidean/LUB plane, any non-identity belineation which has more than one fixed point and is not the identity, is an axial affinity; it concludes with a classification of belineations. To prove the main result of this chapter we need Axiom LUB; this explains its placement after the chapter on real numbers.
