0 Guest Posted July 27, 2008 Report Share Posted July 27, 2008 ...there would have to be some trick involved. Drawing a continuous line, you can only have an odd-node at the start and end points of the line, and this figure has four 5-nodes. However, there are certain tricks you could employ such as clicking the pen to retract the nib (without lifting up the pen), or moving from one part of the figure to another by drawing over a second strip of paper that you lay over the top, etc.I'd like to know if you had something else in mind...

0 Guest Posted July 27, 2008 Report Share Posted July 27, 2008 (edited) octopuppy, it wouldn't be as complex as all those tricks he said you had to draw the figure, but he never said it was all you could draw. you just have to draw outside of the figure to, in the process, create it. that way, each node does have a sixth line connected to it, it's just not shown in the diagram he drew. i'm not really sure how to prove that it works without a picture, and i dont feel like making one right now, but hopefully that's clear enough enigma, am i right?

0 Guest Posted July 27, 2008 Report Share Posted July 27, 2008 (edited) Just realized I crossed a line.. I give up [spoiler=] Just an after thought, if you folded the paper (asuming you are drawing it on paper) in half it become a piece of cake.

0 Guest Posted July 27, 2008 Report Share Posted July 27, 2008 (edited) taliesin almost got it right. all you have to do is not cross the line and follow the other line. so er... good job. um. how do u attach images? edit- ok um. how do u put an image in a spoiler?

0 Guest Posted July 27, 2008 Report Share Posted July 27, 2008 what about that big black line that hasn't been drawn? also, i thought you are allowed to cross lines, but just not draw completely over them Quote Link to comment Share on other sites More sharing options...
0 Guest Posted July 27, 2008 Report Share Posted July 27, 2008 Its impossible to draw. The figure should contain either no odd vertices or exactly two odd vertices. This has four. Quote Link to comment Share on other sites More sharing options...

0 bonanova Posted July 27, 2008 Report Share Posted July 27, 2008 octopuppy and esjohnson are correct in their comments about too many odd parity nodes. jimmyt's suggestion of adding a line can reduce their number to two. The spoiler contains one way to do this. Still, that's not what the OP asks us to do, so this doesn't seem to be a solution.Start at any of the 5th order nodes and draw diagonally to another 5th order node.Draw the inside square.Draw the outside square. This leaves you with the other diagonal. To draw it, make an extra line outside the figure to an adjacent 5th order node.Draw the final diagonal.Steps 4 and 5 change two of the 5th order nodes into 6th order nodes. Again, this doesn't seem to answer the OP Quote Link to comment Share on other sites More sharing options...

Again, the number of lines matters, check my hints Ok I have made the solution and it took me an hour to do it, it is a very clear and precise solution, with only one trick... I will post it when someone tells me how many lines there are in the figure (that is the trick) Also Good Luck Quote Link to comment Share on other sites More sharing options...

0 Guest Posted July 27, 2008 Report Share Posted July 27, 2008 27 is incorrect, may I ask how u got that number? If you draw the lines side by side making them double width but not over each other there are many solutions. Quote Link to comment Share on other sites More sharing options...

0 Guest Posted July 29, 2008 Report Share Posted July 29, 2008 (edited) oh... i wouldn't have thought of that. when you drew the original diagram did u actually make two parrallel lines for all of them? although, following your instructions to the letter i believe my solution would still work Edited July 29, 2008 by jimmyt9574 Quote Link to comment Share on other sites More sharing options...

Question
Guest
Draw this figure with out:
Drawing over lines
lifting up your writing instrument
erasing/altering lines that you have drawn
folding/manipulating the writing surface
Here is a pic i put on image shack, paint is not that great of a program, i will try to get a better one up later
http://img115.imageshack.us/img115/1499/ni...rsriddle5xh.jpg
Also the writing instrument is a standard pen, just to clarify
Also it is 100% possible
Edit: it is a 2D image, and the jagged edges in the pictures are suppose to be smooth,
