Comment on Is this a triangle?

  If a shape has 3 corners and 4 edges, it is incomplete or open and therefore not a shape yet but a collection of edges.

  A shape with 4 corners and 3 edges is not possible. An edge cannot have a corner in the middle of it, that would make it two edges.

    I felt like adding something about the specific case of 180° between edges and a vertice.
    Makes sense.
    And I guess too many vertices means an open set of edges (ie not close, this not a shape).
    I was kinda hoping for a strange edge case, like a mobius strip or Klein bottle.

    I guess a mobius strip is a 2d representation of a 1d paradigm. And a klein bottle is a 3d representation of a 2d paradigm.
    It would be too much to ask of a 1d representation of a ??d paradigm.

  Why the down votes? Bro asking a question and being legit curious, don’t be hating on someone that’s looking to challenge what they know just because it’s trivial to you.

    I feel my comment adds to the discussion and wants more details.
    But it was too simply phrased.
    I guess the details of such a question should be obvious. And if you need the details, the question doesn’t actually add the the discussion… It just seems idiotic!

    I felt like there might be a really cool scenario where a vertice isn’t considered a vertice.
    Like, there actually might be some case on a 2d plane “where actually” applies.
    I’m fine being wrong

  I don’t think that can be a thing.
