While parts of it can be triangular by reason of having 3 finite sides, the whole of it does not have a third finite side so is not a triangle.
NOte that to be a triangle, it would also have to have three vertices, which is not the case.

Even if it were true that 1/9 were a line, which it isn't. rather than merely a rational number, since 1/9 does not have any endpoints, WM still does not have a triangle, at least not anywhere outside his Wolkenmuekenheim. > > My construction does nothing else but to cover every 1 in an > alternative way.

WM's constructions almost never display the mathematical properties he reads out of them, and certainly do not here. > > > WM's sloppy thinking > > Sloppy thinking is not to distinguish between actual and potential > infinity like matheologians do here and on many other occasions.
One can easily distinguish between them. The actual ones occur in standard mathematics, as in the sets of naturals, integers, rationals and reals, among other places, and WM's potential ones only in his WMatheology.
