Hi Pamela

the manual says

typedef Triple<Cell_handle, int, int>
	Edge; 	(c,i,j) is the edge of cell c whose vertices indices are i and 
j. (See Section 28.1.)

so, in the triple (there is an html link to this class from the previous 
lin in the manual)
- first is the cell c
- second is the index i of the first vertex of the edge
- third is the index j of the second vertex

the points you want are the points c->vertex(i and j)->point()

I don't know which points you reach when you use the functions cw and 
ccw, but indeed you are not reaching the correct points...

best
