Not at all. Sets have no geometrical constraints, triangles do.
Most sets are not triangles, including the set you describe above.

On certainly can think of it as a set or sequence of triangles, but a
set need to be a triangle and the limit of a sequence, if it ere ro
exist at all need not be the same thing as the mambers of the sequence
are. For no limit of a strictly increasing sequence of naturals is
