| you know, there's a small program called xeukleides that lets you define a draw with simple commands
(this would be like defining three triangles:
A B C triangle
C D E triangle
(for course adding coordinatesd if you want)
and then defining the lines
t1=line(A,C)
and so on..
defining intersection points
P = intersection(t1,l1)
and finally actually drawing them
draw(t1)
draw(P)
draw(A,B,C)
etc
and it renders you a realy good looking postcript
look at "triangle cetners" entry. It's a bit complex but was done with eukleides
f
G -----> H G
p \ /_ ----- ~ f(G)
\ / f ker f
G/ker f |
