I was asked this question in another forum & my answer was that none of them actually touch, they merely share the same intersect point, however small:I tried to use the following graphic to illustrate my point that they are not two lines but four "squares" whose corners meet at the coordinate 0,0 on a basic graph.Do the corners of Arizona and Colorado touch each other?
If Yes, then Do the corners of New Mexico and Utah touch each other?
If Yes, then How can the corners of Arizona and Colorado touch each other?
Does anyone have a more logical explanation or am I completely off base?
I really appreciate any & all help.
