# How can I truncate only a single vertex of a polygon?

One can truncate all the vertices of a polygon at once with Truncate. I want to do exactly that -- but only on a single vertex. Is this possible with Mathematica 9? How?

I believe you will have to implement this from scratch. You'll need to extract the points from the Polygon expression and work with the coordinates. Have you tried doing this? If yes, where did you get stuck? –  Szabolcs Jan 28 '13 at 23:02
