Erm... Fold 'em up into a paper airplane, head to the roof, and see what happens?What could you do with these relationships around a semi-arbitrarily defined shape?

What do you mean "doing with these relationships"? What did you have in mind? Thank you!
is [relational geometry] for real?
What are you trying to say here? In the first, apparently, you have three overlapping congruent ellipses, labeled A, B, and C. The intersection of A and C only is labeled a' and the intersection of all three is labeled a, and then you have \(\displaystyle a= a'+ \delta\). So a and a' are the areas of the two sections? And what is \(\displaystyle \delta\)? There is no \(\displaystyle \delta\) in your picture.
