| Sep 3, 2011 at 3:37 | comment | added | Joseph O'Rourke | This is a nice solution for triangles, although perhaps there remains a bit of argument to distinguish a double tangency discontinuity from a vertex discontinuity. But that aside, now it is natural to wonder about convex quadrilaterals... | |
| Sep 2, 2011 at 13:38 | comment | added | Gjergji Zaimi | The tangency discontinuities will all come before any vertex discontinuity (for triangles). Also one can distinguish double tangency discontinuities because their peaks are more distinguished. | |
| Sep 2, 2011 at 13:34 | comment | added | Joseph O'Rourke | I guess not, when the circle center is the c.g. | |
| Sep 2, 2011 at 13:22 | comment | added | Joseph O'Rourke | @Gjergji: I am uncertain of "the first three." Could not a discontinuity caused by an internal vertex be interleaved with the tangency discontinuities? | |
