发帖数: 9 | 1 I cannot use a simple way to present my proof. And if you
cannot verify the correctness of my answer, you cannot
justify my proof, I think. I am not confident about my
answer. Can somebody verify my answer?
The general idea is the number of regions is equal to the
number of edges (not including the edge of the n-gon) plus
the number of crossing points (if such a point is on more
than two edges, it is more complicated, and I hope my answer
has considered it) plus one. |
