Can you remind us what a Riemann triangle is? It doesn't have a Wikipedia entry, and surely that is the standard for requiring someone to explain it
In any event whatever you're doing, 630 - 270 = 360, and angles are congruent mod 360. So you haven't done anything except run around in a circle.
ps -- On your FB page you copyrighted this? I hate to tell you, you don't have any intellectual property rights to the fact that adding 360 degrees to an angle gives you back the same angle. But I'd love to see an explanation of what all this is about.
The picture on the right looks like a kidney bean. Is that part of the plan?
