Triangular ?
A cowboy rides through an Indian village.
He see's an indian squaw sitting on a deer hide with her son.
Then he see's another squaw on a buffalo hide with her son.
Then he see's a squaw on a hippopotamus hide with 2 son's.
Hmmmmmm, he thinks........the squaw on the hippopotamus is equal to the sons of the squaws on the other two hides.
