| Jun 9, 2015 at 15:49 | comment | added | Yoav Kallus | @JosephO'Rourke I believe the OP wants the endpoints of the segments to be points on the curves $A$ and $B$. A (filled in) triangle with vertices on $A\cup B$ is not necessarily a union of segments with endpoints in $A\cup B$. | |

| Jun 9, 2015 at 12:08 | comment | added | Joseph O'Rourke | Isn't a triangle a union of line segments, with one endpoint at a particular vertex? | |
| Jun 9, 2015 at 9:53 | comment | added | Joseph O'Rourke | See the related earlier question, "When is the hull of a space curve composed of developable patches?," whose answer is: Always. That question includes images of hulls. | |
