Correctly following the rules of construction results in a valid proof. That proof is in the steps taken, not the final diagram, because there's no way to tell

Correctly following the rules of construction results in a valid proof. That proof is in the steps taken, not the final diagram, because there's no way to tell by looking at a diagram if the rules were in fact followed.
Part of the point I was making is that proof by construction isn't really a "visual proof" at all, it's a proof system where the steps in the proof are added to a diagram, according to exact rules which must be followed at every step.

- lupire 3y agoHow do you know the proof is valid for the theorem you are trying to proof? You have to check the logic of the construction, to know things like which measurements are exactly equal. So the visual part of the construction doesn't suffice. It's the same issue as the infinite chocolate triangles glitch.
