To think this simply can't be done?!

Help. I have to solve this problem by tonight.
I need to draw this shape without taking the pen off the paper or crossing a line already drawn. Can anybody help?

Is this a serious post?

Google and YouTube are your friends.

That's a different shape. Plus he crossed a line already drawn

Actually this is more what you want.

Why do you have to solve it by tonight?! I’m intrigued!

So it is impossible I think. Folding the page is the same as lifting the pen.

Fucksake, wish I hadn’t bothered posting the second link now. Would a “thank you” have hurt you?!confused

Even if the first video didn’t meet your needs, it would have given you the idea that typing “draw x in box” in google would have led you to an answer.

Manners cost nothing!

I don’t think folding the page is the same as lifting the pen. Surely it’s an exercise to get you to think laterally like that? I’m terrrrrible at stuff like that, always need to be told 😄

Ellisandra Tue 19-Mar-19 12:40:54

How is folding a page the same as listing a pen?!!!
It’s a totally different operation.
Again, a “thank you” wouldn’t hurt hmm

You have four vertices of odd degree, can't be done.

ScreamingValenta Tue 19-Mar-19 12:42:57

Use a retractable ball point so you can keep the pen on the page without drawing unwanted lines.

StayAChild Tue 19-Mar-19 12:48:54

I wonder how many of us are sitting with pen and paper trying to do this grin

Rubusfruticosus Tue 19-Mar-19 12:57:00

You have to both enter and leave each of the vertices, except for the first and last in the path if you end in a different point to where you started. So all the vertices need to have an even number of lines coming out of them (if ending where you started), or two can have an odd number of lines (start and end points). Otherwise you can't draw it.

We used to do one at school but that had a little roof on it. Which it turns out I can still do 40+ years on! But it doesn't work without the roof.

<No help whatsoever>

if it's joining the dots, you go beyond the outline of the dots, if you see what I mean.

NannyRed Tue 19-Mar-19 13:01:29

It is possible! @Ellisandra even posted the perfect video showing it being done but you think folding the page is cheating. What a defeatist attitude.
You’ve had the answer, and I don’t know why you expected someone else to find that for you.

Genius!

Bartlebysleftshoe Tue 19-Mar-19 13:16:23

I don't think that it can be done without the folding paper method.

This seems to explain why, there will always be a line that you cannot draw.

DontCallMeCharlotte Tue 19-Mar-19 13:17:13

Ellisandra's second link did do the job and fitted the brief. If they're going to give you something otherwise impossible to do, then you need to sink to their level as it were.

So now you owe Ellisandra your thanks and an apology because she was right.

grin

Ellisandra Tue 19-Mar-19 13:20:21

Thanks!
OP gave scant information so who knows what it’s for and why the urgency 🤣

If it’s for a maths course, then fhr correct answer probably is no, with a side of explaining vertices.

If it’s a more general question - then it’ll be lateral thinking and the folded paper is correct.

Reaa Tue 19-Mar-19 13:22:29

The box with the roof on, start bottom left and go up into the roof before doing the line under the roof and then the cross bit.

Goodadvice1980 Tue 19-Mar-19 13:24:13

Start by drawing a backwards Z and take it from there (from memory!).

TinklyLittleLaugh Tue 19-Mar-19 13:24:55

Is Rumplestiltskin on your back OP, threatening to take your firstborn?

steppemum Tue 19-Mar-19 13:27:45

can I just say, you HAVE to cross over a line already drawn in order to do the cross, it is simply is not possible to draw the second line on a cross without crossing the first line!
