    This one is enclosed and contiguous though, the lines of the triangle end where the circular line starts. (The rest is just a drafting residue.)

      No, it is 2 contiguous regions. The line of separation is the bounding line of a “shape.”

      Otherwise, the entire whitespace outside of the region is also part of the shape, as is anything it touches.

          Well then the line of separation means nothing and then you’ve lost two right angles to the contiguous void.

              Without a distinction of where the cube begins or ends it does not because there is no cube and there are no angles.

                Fun fact - there are no actual cubes anywhere in the universe. All geometric shapes are an abstraction. There are no cubes and no angles, so that checks out.
