Postulati d\'ordine

Axioms/postulates of order
Italian term
Postulati d'ordine
Geometria nel piano euclideo
Concetti primitivi, postulati di appartenenza, postulati d'ordine.
I postulati di appartenenza, se non ho capito male (data la mia ignoranza in geometria) dovrebbero corrispondere ai postulati di Euclide (pertanto il tentativo di traduzione è "Euclid's postulates). Tuttavia, non trovo un'idea di traduzione per i "postulati d'ordine". Qualcuno ha un suggerimento?
Grazie in anticipo

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

Axioms/postulates of order
Postulati dell'ordine
Danno il concetto di ordine sulla retta e nel piano:
Data una retta e su di essa due punti distinti si puo' scegliere sulla retta un verso per cui il primo punto preceda il secondo ed il secondo segua il primo
Data una retta e su di essa due punti distinti esiste sempre un terzo punto che si trovi compreso fra il primo ed il secondo (in pratica significa che i punti su qualunque segmento di retta sono infiniti)

Axioms of Order
When B is between A and C then, A, B and C are distinct points lying on a line and B is between C and A.
Given a pair of points A and B there is a point C so that B is between A and C.
If B lies between A and C then A does not lie between B and C.

This assumption is based on geometrical intuition, and indeed, it cannot
be deduced from Euclid's postulates; to make it strictly demonstrable and independent of any reference to intuition, a special group of postulates has been
added to those of Euclids, they are the postulates of order. One of these-to give
an example asserts that if A, B, C are points on a straight line 1, and if B lies
between A and C, then B also lies between C and A

Discussion
I don't believe that "postulati di appartenenza" are "Euclid's postulates", and I suggest posting a separate question for that. These are pro terms.
