Union[...options]

I'm in the process of creating a lists of polygons from other lists of 
polygons  (triangles in this case). Thing is the function that creates 
the new list of triangles from the old one, does produce overlapping 
triangles. What I actually get is a list of lists of vertices and my 
idea is to discard a triangle if the distance of each of his vertices 
from the vertices of any other is less than, say, 0.1. Can I use Union 
and a sametest? What I'm unable to write down is a feasible declaration 
of this test. Any help would be appreciated

Thanks in advance
