Do the legs have to be even?
- istjohn 5y agoYes. Imagine a chair with one pair of diagonally opposite legs very long and the other pair of legs very short. On even a flat surface it is impossible to touch all four legs to the floor simultaneously.
- twic 5y agoNot even, but the feet have to be coplanar.
- caf 5y agoAnd since the spacing between the feet is obviously irrelevant, that further implies that it's always possible to find 4 coplanar points on the surface arbitrarily close together. Or arbitrarily far apart.
