Hi , all

I'm currently use Mathematica 4.0 and I need to compute 
fastly the angle between  the vertices of a polygon.
The statement of the problem is :

Let be (P) a polygon with n vertices point, I want to calulate 
the angle (T) between all consecutif edge. 

(P) = {P1, P2, P3,.............,Pn}
P1 is a 2 or 3 dimension point.
angles between (PiPi+1, Pi+1Pi+2) i = 1, n-2;

I have about (100000 points in polygon)

Thanks in advance
