comment Prove that 2 of 3 triangles sharing one side overlap
Point taken. I have added an explicit question. I like the idea of dividing the plane as you suggested and will think about it some more.

comment dy/dx when x and y are functions
I did not think about the inverse function theorem. In any case, when you write $y(t(x))$, are you treating $x$ as a dummy variable? Your last statement gave me an idea: Perhaps $dy/dx$ is the function whose value at $t$ is just $y'(t)/x'(t)$?
