Triangle Puzzle
OK - heres an interesting thing for you - apologies if you've already seen it but:
http://www.sterling-casino.com/ukbug/trigrid.gif I'd love to run this by my old maths teacher at Rhyddings it'd surely do his head in. |
Re: Triangle Puzzle
In the spirit of fun I will defer telling you the answer :)
Suffice to say... Ya can't beat the old ones can ya. BTW... Do you know the answer or just posting the puzzle? |
Re: Triangle Puzzle
Yeah, I do know the answer. Although I didn't work it out for myself. I spent ages when I first saw it trying to work it out!

Re: Triangle Puzzle
It's a trick of the eye. all is not what it seems.

Re: Triangle Puzzle
I think, and this is only a guess, that the area of the second triangle is different to that of the first because the angles change, hence the extra square!. Please tell me someone!! ....am I right????? ???

Come on! Explain it!

Re: Triangle Puzzle
I know, i know!!! Erm basically both hypotenuse of the two triangles within the triangle arent at the same gradient (angle as each other). When theyre changed around it allows the yellow shaped to move out slightly.
Its kinda hard what im trying to explain, but if you look at the first traingle shape made, the hypotenuse of the whole shape bends in slightly, taking up the area of the square which becomes available when the shapes are moved to the position of the second triangle (if you look at the hypotenuse of the second triangle made by the shapes it bends out slightly, allowing for the extra square to be available). Kinda hard to explain, but i hope you all get the drift of what im saying. ;D ;D ;D ;D ;D |

Re: Triangle Puzzle
Whats a hypotenuse when its at home ?
The answer is that both triangles are not the same size. We can see the straight line along the bottom and the straight line up the right side are the same.. Its the angled line from top right to bottom left thats different.. On one it bends out slightly.. on the other it bends in slightly.. the slight bend is hard to spot unl;ess your told and affords enough free space on both to make up a whole square.. As they curve in or out then its most noticable half way down the line..Find a square half way down and you will see theres a slight difference in how much room a square takes up along the lines.. like I say.. enough to make up a whole square if ya add them together |
Re: Triangle Puzzle
So what Harry is saying is that neither shape is a triangle, but a tetrahedron. The hypoteneuse (long bit) on one is concave and on the other is convex.Can all be proved by trig, which is where the Fibonacci guy comes in. The sequencing of the shapes along with our instant assumptions fools the eye. :D
