comment Finding the largest triangle inscribed in the unit circle
@YvesDaoust Yes, of course this is enough. I wasn't implying that this isn't enough, any argument that the solution exists will do.

comment Finding the largest triangle inscribed in the unit circle
@YvesDaoust Yes, that's what I actually meant. I just mixed up smoothness and continuity in my comment. I just wanted to point out that the "Make other triangles larger" argument for completeness also requires that a solution exists.

I guess we should at least mumble something about compactness and smoothness (or equivalent) to show that a largest triangle exists.

comment Soft question: Union of infinitely many closed sets
BTW: In your example with growing disks you state that the union of growing disc cover the whole plane which is open. But it is also closed (clopen), just like the empty set.

comment Can a Rubik's cube be mapped knowing only two sides?
Well, strictly speaking it shows that knowing two opposite sides does not suffice. "Looking at only two sides" seems to imply that the sides are choosen by the solver, so he might choose adjacent sides (Ok, we now know that this case is also closed).
