Quote -  Most hobbies don't use terms like "Quadratic tesselations".  OURS does. :laugh:  A quadrangle is a quadrangle.  I watch to much public television.:lol:

You think that's bad, we also have "degenerate triangles" which are triangles where all three vertices are each at 180 degree angles to each other.

But I try not to be obtuse about it. ;-)
