This could be the start of a maths' exercise: "ABCDE is a pentagon."
In french, we would say "nom" (name) of the polygon to refer to "ABCDE", while "nature" of the polygon would refer to "pentagon".
Reading wikipedia, I figured out that, in english, "pentagon" is the name of this polygon. So, what is "ABCDE"? Is it possible to call it the name of the polygon, too, or is there any specific word?
Some context: I need a correct english word that I can use as a variable name in a software I develop, in order to store, for instance, the string "ABCDE" as a polygon's property whose name would be understood by anyone. For instance, if I write
polygon.name, I guess anyone would guess it stores something like "triangle" or "pentagon" etc. Now it's about this "ABCDE": I cannot store it in
polygon.name too. So,
