Facebook gets cranky about it if they can't find any FB cookies in the browser, is how I understand it. Though it's not likely to be an especially stable policy.
About a thousand years ago, I remember getting taught an alternative approach to conic sections; a parabola is the set of points equidistant from a line and a point, sort of thing. It sounds vaguely like you're headed toward a similar set of definitions for triangles.
