Is a seemingly straight line a shape of Space? ________ Apparrently not according the article below.
..."The basic difference, though, between “shape” and “form” is that “form” is in 3D while “shape” is plain 2D."...
So this this pattern{?} as follows \/ i,e. a single angle defined by two lines, also is not a shape of Space, because it does not define an area?
Is \/ truly even a pattern of Space? Maybe a pattern requires requires a repetition of angle ergo /\/ is two angles defined by three lines, however, the angles are in opposite directions. Can this truly be called a pattern of Space?
Ok so here two angles in same direction, and a third angle in other direction /\/\. Is that closer to being a labeled as a true pattern of Space?
/\/\/ and with this pattern of Space we have angular pattern of Space symmetry because, we have two angles in same direction and two angles in same direction that opposite direction, however, they are not diametrically 180 degree opposites, or at least their not diagonal opposites as associated with a diagonal between two points or nodes as follows <> , well actually to do this means we have to use four points/nodes and 2D area shape of Space.
However, in so doing we skip over the less complex, triangle that goes back to a previous semi-2D shape of Space /\/\ wherein we have three angles but require 4 lines to do so. So, Mother Nature does what with shapes of Space?
/\ or Y both have three angles and only use three lines to define a shape of Space, however, one encloses as a finite 2D area, and the other does not.
Finally we get to the birds-eye-view of a 3D { volumetric } tetrahedron \Y/ which is combination of the previous two, altho, if anyone of the four vertexes of the tet is moved to the its diametrically opposing triangle opening, we have a 2D subdivided triangular area and now we have 9 inside angles,
three on inside circumference, and three around central vertex. Yes, in all of the above I'm excluding consideration of exterior angles.
Have arrived at a conclusion as to what is the shapes of Space? Yes and no, because of course there are many more we have not included. Does and infinite amount exist? Yes conceptual infinity exists. In actuallity a finite number can only exists with a finite occupied Space Universe, with a finite period of Metaphysical-1 time.
