 Asker: Maybe I'm missing something here: I get the impression that "circle diameter" does not make all too much sense in the sentence it is used in: "puis ensuite une droite qui peut être UN DIAMÈTRE DU CERCLE." "... that can be a circle diameter" Would you be willing to comment on your suggested translation, in relation to the sentence it is used in? Could you maybe paraphrase what you think the author is trying to say?

-> thank you !

neutral  Tony M: Not really, it makes all the difference that it is A diameter of THE circle, and the word order is crucial here.

explanation

Explanation:
the straight line in question may be one of the diameters of the circle.
After all, although all diameters will have the same length, they can start anywhere on the circumference of the circle, crossing to the other side via the centre to arrive at their opposite point.

Think of a circle, draw one diameter, now draw a different diameter and so on .... you'll see what I mean

Without knowing the purpose of this exercise, it's difficult to be more precise than the source text extract we see in the question.

'... une droite qui peut être un diamètre du cercle'.

Then, the text seems to be saying that you have:
- a circle
- a set of spirals
- a straight line, anywhere on the page - *including the possibility that it may pass through the centre of the circle and therefore constitute a diameter of the circle*.

The mathematical significance of the sentence may be that if the straight line passes through the centre of the circle (and is therefore a diameter of the circle), that is a special case in which the points of intersection of a spiral and the line will be in a regular progression; if the line is not a diameter the progression will be irregular - and may different for each spiral.

 Asker: I most certainly enjoyed reading your takes on this. The purpose of this exercise is to prove that in a network of curves, a circle is the symmetrical figure of a straight line. Maybe it can help if you read the text that follows: "Nous mesurons les arcs de spirale qui vont du cercle à la droite, nous en prenons le milieu, nous joignons ces milieux, ce qui définit une courbe C. Lorsque les conditions angulaires sont telles qu'au point d'intersection, la tangente à la courbe est perpendiculaire à la tangente aux arcs spiraux, nous disons que le cercle est symétrique de la droite par rapport à la courbe C dans un réseau spiral."

agree  Tony M: Yes, that's exactly the way I read it to: any straight line that may (or may not) be a diameter of the circle.
