I came across an interesting question online that was about vertices of quadrilaterals. I am still stumped as to how to find the answer of this solution.
The question I found was:
Is it possible to find 4 points that are the vertices of 2 different convex quadrilaterals? If so, what is the maximum number of convex quadrilaterals that can have the same set of vertices?
I do not think that it is possible to find 4 points that are the vertices of 2 different convex quadrilaterals, but I am not sure if what I think is wrong or right? If my conclusion is right, could someone explain why please?
Thank you very much.
