You know these puzzles!? There is a drawing and you have to find out how many triangles one can see.

But that's boring. More interesting is it to write a perl script that will solve it for you.

I once did so and will post my solution as a reply to this.

Let's see your scripts. Solve the puzzle given at the page linked above. Should it not be there anymore, here is an ASCII-"Drawing" of it. 

                 (A) 
                 /\ 
               / /\ \           
            /   /  \   \        
          /    /    \    \      
        /     /      \     \    
      /   (C)/        \(D)   \  
 (B)/_______/__________\_______\(E)
    |  \__ /            \ __/  |
    |  (F)X__          __X(G)  |
    |    /   \___  ___/   \    |
    |   /     ___><___     \   |
    |  /   __/   (H)  \__   \  |
    | / __/              \__ \ |
    |/_/____________________\_\|
 (I)                            (J)

The letters given in my "Drawing" are those I used in my script to mark the nodes.
