Yeah, I guess the assumption it takes is that there aren’t larger topographic changes for the other legs between their points, and that the legs are equal length. But I like it, it’s a fun one I’m trying next time
Right. Somehow I was thinking only of the floor being uneven, not the table legs. Surely it’s trivial to have table legs sufficiently different to not fit on any arbitrary shape of floor?
Haha yes :) I was somehow thinking for this type of problem, the usual case is the legs are uneven… because if the floor is uneven or not level the table will be uneven or not level regardless of whether it has 0, 1, or n legs. But I guess the problem is about “wobbling” not about being level.
Does it require any arbitrary constraints on the topography of the floor?
Sorta. The function height(angle) needs to be continuous. From there it’s pretty clear why it works if you know the mean value theorem.

This can’t actually work if the floor is a level plane right?

Yes, the floor has to be bigger than the chair.
