5 Dots

[ThePrototype609]

sooo easy :/

[OMFScience]

00:31 - ok whats the catch -_-

[DeathScytheHell23]

Everyone know's it is impossible in the second dimension. What is the point of having all of these impossible puzzles that can't be solved in the second dimension. How bored do you have to be to think of an impossible puzzle. Hey, I know, let's make a puzzle like this one where you have to connect six dots. That is impossible. Let me just throw that on youtube. Oh, and by the way, there are no rules for puzzles. Just draw a single strait line through all of the dots and you have solved it. Tada

[mrBorkD]

i used the 4th dimension

[mrBorkD]

impossible*

[acdc10133]

Impossible. This is discussed in graph theory, The graph you are trying to draw is K5, 5 points where each point is connected to every other point and you can't draw it without crossing lines. Not on a plane however, but you could do it on a torus :), which is just a doughnut...

[657viper]

@acdc10133

Just learned about that last week. Haha. Yeah, It's a planar graph problem which can't be done since it's the k5 graph. My professor also spent today talking about toruses as well haha it was interesting. He related it back to the game Asteroids.

GAY SONG

[hamoan66boi]

impossible...

[KurdtKobain09]

.....how is this impossible?

[manofdale]

lots of solutions:)

try this: take two tetrahedron and join them together at one face so you have a shape with five corners that you can connect each corner together.

another one: You will see that on a torus surface you can connect five dots easily.

[miranon]

impossible...

[Killawale777]

if is is lol

[Quiet0wing]

ITS EASY just draw a straight line through all of them......just one line....connects then all to each other

[azn6190]

@Quiet0wing

did u even look at all the rules?

[xthatoneguyx]

check the last rule.. hahah

[newgrounder2]

sheesh youre stupid

[Coolioitbro]

@Quiet0wing last rule dumb @ ss

[Singerazboi100]

Rofl replying to something from 2 months ago Dumb @ss

[Coolioitbro]

Time doesn't make any difference.. WOW your stupid

[Singerazboi100]

And you are immature.

[sociallyineptguy]

This is so easy it isn't even funny. All you need to do is think 3D.

Connecting all the dots should be easy enough for anyone until you try to connect dot 3 to dot 5. Then just connect dot 3 to dot 5 by bringing the line up and over dot 4. Imagine the line coming off the paper towards you like a 3 dimensional drawing. It never touches dot 4 at all or cross any other lines.

There's no rule that says you must think or solve this in 2D. All u have to do is open your mind to all the possibilities.

[serhyrania]

@sociallyineptguy

you might as well draw a wormhole inside the very dots, that way the lines are so small you dont even have to draw them :P

[jan430]

thats easy make a star figure it have 5 dots which need 10 lines to conect them, am i right?

[gwani]

Forget it! Unless there are any dirty tricks involved there is no solution. If i got the rules right, what you are trying to draw is a "planar" (can be drawn without crossing edges) version of a complete graph on 5 vertices (K5), as its called in the mathematical field graph theory. It can be proven that the K5 is "non planar", meaning its impossible to draw it without crossing edges (Google for proof)

[gwani]

Google for

K5 "non-planar" proof

...the site labelled "Graph Theory" @ personal kent edu explains it quite well, including mathematical proofs.

[suupertramp]

theres probably a dirty trick to the solution

[Immelx]

That has to be the most annoying song ever...

[Xax86]

Impossable? No, because impossable isn't a word...

[ScrewedOnBackwards]

prove it?

[harrypotterfreak272]

.........um..........what!!!??­?

[Dapinquin]

wat een kankerliedje!

[Bown3d]

dapinquin of niet kk verrot eerste tjap die nederlands praat faka mn

[xHALOxCUBERx]

lol solved as an 11 year old hahaha germans rule

[csarvids]

solved!!!

[kolon31]

_._._._._._ thats how you do it...

[huntingfreak101]

u fucken german

[wholieo]

Here are 2 solutions to the puzzle. Both solutions comply with all the rules.

Solution 1: simply draw all 5 dots on top of one another, drawing the connecting lines becomes simple.

Solution 2: draw the 5 dots in a row on the inside of the hole of a doughnut, you will loop a connection between 1 and 5 around the inside and a connection from 2 to 4 around the outside.

This should make it easier for those that think they had a solution to post a video.

[bgg0071]

solved

[OperationFailure]

Impossible* [impossable in the video.]

[SICARIO2]

i tried but i think its very hard or impossible :/

[SICARIO2]

mmm i think i did it lemme chek

[SICARIO2]

its possible whats the page of the that puzzle or where u find it ?

[TommygangX]

someone came up with it in algebra class a while ago, and nobody could solve it..

[SICARIO2]

:)...

[loicroure]

@TommygangX because it's not possible...

[GameboyPocket]

Maek moar Squaerz

[lachcat]

hä?

its really bad if i want watch an english video and i dont know whats the important thing -.-*

[fredinlalaland]

psh easy

[UGSETH2]

catchy song :)

[sycodeathman]

i did it

[thehymner]

i dun no, did u just solve it 3 time for us alrdy?

[Nelesu]

swein

[lhynuel11]

lolz

[m07p13]

This is the K5 graph in an isomorphic form so it is impossible. (without making bridges :D)

[TimeShiftBand]

hey there,

I did it - you need ten lines... but wait - I'm going to ma a video for you to explain that ;)

I guess it isn't as hard as you thought but it's tricky indeed :D

[UGSETH2]

thats better than the loosers saying that they can do it so much better than that without proving it :)

[Raverspike]

The music isn´t by "Der Prinzen". They are "Die Prinzen". Only a small difference.

In English there is only a "the" for male female and neutral. Still a simple language...

[LKV16]

I have no proof but i think it's not possible.

[Merssedes]

В теории графов доказывается, что граф не планарен (невозможно нарисовать на плоскости без самопересечений), если в нём содержится один из двух графов: 1) полный граф с 5 вершинами; 2) полный двудольный граф с 6 вершинами. (теоремя Портнягина-Куратовского)

[KesavaAVP]

OMG fuck that music, seriously.

"We", as a class, had to listen to this rubbish for over like 10 times because it was part of some stupid TEST!

[Demonshadow1988]

I would like the challenge more if you were a german...like me

[asdfasdsafsd]

Who said the dots have to be in a straight line?

DUN DUN DUNNNNNN!!!!!!!11

[xoxfriedricexox]

i did it... took me 5 minutes rofl. its on my account.

[mi4mercenary]

its not exactly hard

[ShankTheShazbot]

Write them on a piece of paper, now fold/tear the paper between dots and you can make it 3-D drawing a line on both sides of the paper.

[cruddy3000]

Why are you using a Dia Prinzen song kissing if forbidden lol

[butterflyknife000000]

if the dots were 3d then you wouldnt cross the other lines you would pas under the line not crossing but getting to all the points

[mikan25b]

it's not really hard. Just have to write the dots a bit different like this: . . . . .

Now it gets easy.

[fr0stb1te]

impossable isnt a word

[manos2fatality]

Is there actually a solution?

TommygangX, do you know the solution?

[punkxsuyre]

..i dont think it can be done but im no math maticion

[darkseraph2009]

Do the dots have to be arranged in a line? Just wondering

[isrsan]

i did it

[TimwiTerby]

The problem is equivalent to showing that K5 is planar. However, K5 is not planar. (I found a proof for that by googling, but YouTube is not letting me post the URL here.) Therefore, the problem as stated is impossible.

[n3o59hf]

Imagination :) Are there any rules against placing lines in 3d space? If not, then ... its solved

[TommygangX]

It would be solved if u can use 3d space yea, but try in 2d, nice use of imagination tho.. :)

[NoPlaceToRest]

Until proven otherwise, I believe that's impossible. Here's my reasoning: 1-4 and 2-5 have to be on different sides of the imagined line no matter what, so you might as well draw them first. Once you're drawn them, 1-3 and 3-5 are determined as well; they, too, are always on different sides of the line. Now, 2-4 would have to be at a different side than both 1-3 and 3-5, but that's impossible.

[NoPlaceToRest]

Thanks for making this video, though. It was fun thinking about it. :-)

[TommygangX]

But you could also go all the way around the dots and then connect them them all that will only leave dots 3-4 not connected , i think it has to do with what lines you draw first.

[isrsan]

i did it

[neophyte0]

you're thinking a bit too linearly. lines can go around and between other dots. For instance, the line connecting 1 and 4 could go between 2 and 3, and thus not be entirely on a different side from the line connecting 2 and 5.
