The goal is to trace a line with your pencil across each edge on the box only once without crossing the vertices or picking your pencil up.

Note that this "box" contains 16 unique "edges".

Prove why this is an impossible task regardless of where you first place your pencil.

i read a few of the posts on this one, my friend gave me this and said to cross each line once and without crossing your owen line right. is it possable or the the answer just impossable. i dont really see the 3 trianlges that Erik O. said. is anyone able to do a illustration for me ive been tryen to figure this out for ages and ive got about another 20 ppl hooked on it lol like really hooked.
