This is the question.
I started editing it going through the points in math.stackexchange.com/help/…
- I am studying mathematics at any level
- it is a mathematics concept understanding related question
- it is a mathematical puzzle
I am not sure if this is a research question as this question occured to me when thinking about an exercise in a Geometry I. problem book, but the thinking process that led to it seems to resonate with what might be involved in research level problem solving.
