  The part showing the angle is not part of it. They should’ve made it a dotted line or something.

    Thank you that was helpful.

  That sounds like the definition for convex shape, not the general definition for a shape

    it doesn’t have to be a straight line between points eh

    • lunarul@lemmy.world ⁨3⁩ ⁨months⁩ ago

      The it does meet the definition

    You’re the second person to have made that suggestion to me, but no.

      If you’re talking about straight lines, then yes, that’s how you define a convex shape. If any uninterrupted path can be taken, then the OP shape does satisfy the condition.

  Depends how you define a shape. I don’t think it’s a polygon because it doesn’t have straight lines. Technically a circle also isn’t a polygon by the same rules, but circles have their own special little clubhouse. Sure is a shape though. I think this… thing is also a shape. Just not a useful one.

    As it was presented in the OP, I don’t think it is a shape. If I get two squares and stick them next to each other so one side of each is touching, have I suddenly got one rectangle? Or do I still have two squares with a border between them?

    Someone else posted an amended version with the internal lines removed. The equivalent of taking those two squares and removing the border between them, so you would have just one rectangle.

    Idk seems very useful to me, like if I need a paperweight or doorstop

  I couldn’t find any definition of geometric shape that uses that criterion, including Wikipedia which also has a 5-pointed star shown with 5 line segments labelled as a shape: en.m.wikipedia.org/wiki/Shape.

  The meme is wrong because squares are polygons by definition, which by definition are made of line segments, but this image has a curved shape.
