One of the most typical tricks I have found in humanity is to see the little small one [triangle] and miss the big one and the big one is the one that counts. Then I told him he drew four triangles. And he said, how did that happen? Well, they are spherical triangles and there is a concave little and a concave big as viewed from inside and a convex little and a convex big as viewed from outside.
Convex and concave are not the same; so there are inherently four. In fact, you will always find that there are four there. Four is the minimum and when we get t o any kind of system there is always four there. You will get used to that fourness and get used to not allowing yourself to become overconfined and looking at the little ones.
