The key is true containment, to rule out the extremely unlikely case of a point sitting exactly on a boundary. | |

| Jul 23, 2021 at 8:24 | comment | added | TigerLily | You're right, thanks. But I don't think a little politeness will cost you anything. | |
| Jul 23, 2021 at 8:22 | comment | added | Erik | Centroids are points. If you are able to demonstrate that a point can be contained by several not overlapping polygons, you shouldn't be posting here, you should be writing a paper and getting ready for you nobel prize. | |
