Doesn't need to be 3D

 

[Neffneff]

nerf, then no not confident ;P

 

[Neffneff]

its not sommit stoopid like make a triangle with 3 of em, the use the fourth to cut it in half, making a small triangle at the top and a KINDA square at the bottom? yer know, if you dont believe in right angles?

 

[elisera]

Nope, all the matchsticks stay whole Neffneff

 

[Neffneff]

no i meant cut the diagram in half, sec ill mspaint what i mean, though its obviously not right

Now you are asking the right sort of questions Neffneff but I won't answer them for you.. you have to figure it out for yourself!

well there is only ONE definition of square -

Having four equal sides and four right angles.

anything else isnt actually a square.

so are you asking for a square or a random shape of 4 sides?

 

[elisera]

Rightio, I'm off home. If I get a chance I will check again later to see if anyone gets it right. Otherwise you will have to wait until tomorrow monring!

Have fun guys

Incorrect.

 

[Calaen]

hmm im going to go to bed thinking of you and this puzzle

 

[Neffneff]

 

[Neffneff]

does a cross made of 2 matchsticks count as a swaure? i mean, it has 4 lines, and 4 right angles?

 

[tris-]

well wtf then i did that the first go.

thats not a square, so why was square an objective?
thats a trapezium

 

[Calaen]

that is a very questionable square, as Tris say a square is equal on all sides with 4 corners

 

[Neffneff]

 

[Calaen]

thats the boy

 

[Pirkel]

If it doesn't need to be a square like it's described in the dictionary (A plane figure having four equal sides.) it is actually piss easy.

But then you shouldn't have called it a square but a "Shape with 4 corners" or something.

I would have known it in seconds it's the "square" bit that got me confused

 

[Neffneff]

btw if you follow that link you have posted there pirkel you will see there is a few other descriptions

number 3 in particualr seems interesting to me.

 

[Neffneff]

 

[tris-]

apparently all sides have to be visible and not imaginable

 

[Neffneff]

yes, the L shaped square is all there? dont think square as in 4 corners, four sides, because it is impossible to do that according to the question, after all a square has 4 corners, and a triangle has 3 corners, yet we had to do it in less than 7 corners.

think square as in tool you use to check right angles. you get L shaped things for that.

 

[Outlander]

what a load of bollocks imo!

 

[old.Tohtori]

Three matches in a triangle, one in the middle. So there's two triangles that would form a square.

Nobody said anything about the square being whole *grin*

 

[tris-]

this whole thing is a freaking shambles.

 

[Pirkel]

Rofl Neff very interesting way of solving it

No your first solution:

Was what topicstarter meant (I think) however her description of the shapes required were a bit ... unclear?

Had a mate who's a mathteacher (poor him) define it for me: "A square has 4 sides the same lengths, 2 pairs of parrallel sides and all interior angles must be 90 degrees" so naturally I discarted that solution as that shape doesn't meet those requirments.

 

[Neffneff]

cant be the first one i did, as it has 7 corners, therefore doesnt fit origianl task.

 

[Neffneff]

its gotta be the last one i did, as its the only "square" that can be made properly, and with less than 7 corners.

 

[Pirkel]

cant be the first one i did, as it has 7 corners, therefore doesnt fit origianl task.

Doh

Ah well never mind me then. Maths never were my strong side

 

[Naetha]

cant be the first one i did, as it has 7 corners, therefore doesnt fit origianl task.

I dunno, again it goes by what you mean as corners. It has 3 corners that I can see, 7 internal angles though, but since when have they indicated corners?

But then if the puzzle poster classed a trapezium as a square, then anything goes I guess!

 

[chretien]

What about this?

 

[Outlander]

What about this?

4 matches?
