| Aug 30, 2019 at 10:19 | comment | added | Ivan Meir | @CJDennis True but the point is that the conjecture wasn't part of my question, it was in my discussion of the question so I wanted to include an update to this, not answer my original question. I think this is ok as opposed to specifically answering your own question in your question which I agree is generally not! | |
| Aug 30, 2019 at 10:10 | comment | added | CJ Dennis | Just because you later realised that a conjecture was wrong doesn't make it a bad question, or need to be pointed out in the question. The answer does that perfectly well, and it doesn't reflect badly on you. | |
| Aug 30, 2019 at 7:35 | comment | added | Ivan Meir | @CJDennis It actually wasn't an answer to my question rather a refutation of a conjecture that I posed as part of my own observations related to the problem. | |
| Aug 30, 2019 at 4:02 | comment | added | CJ Dennis | You shouldn't update your question to include an answer. | |

Corrected mistake in area formula, should be 1/2 rather than 1/n at front.

Added counterexample to area conjecture.

Clarified meaning of "smooth motion" and square example.
|
| Aug 28, 2019 at 10:54 | comment | added | Ivan Meir | @WalterNeff I mean a continuous motion that preserves the side lengths. In the case of a square squashing to line I meant that you take opposite vertices of the square and move them together keeping all sides equal so that the squares becomes a rhombus of smaller and smaller area until the area vanishes. I'll add this as a clarification to the question thanks. | |
