At last a puzzle forum!! I have been looking for some genius to give me an answer to this puzzle I seen. I just don't understand how it can be done. It is the one with the triangles - I'm sure many of you have seen it.
It is the 'amazing riddle' on the main page here:

I hope someone can show me how this is done - it is driving me nuts!
Thanks.

I won't tell you the answer explicitly, but I'll say that you can do the same trick with a 3x5 triangle, a 2x3 triangle, and shapes that look like this:
------------------- --------

-------- | | --------------

Hopefully those Badly Drawn Diagrams[sup]©[/sup] are good enough for you to be able to see what I mean.
That version of the trick will work in the same way, but the reason it works will be a bit more obvious.
There's an excellent page on this site somewhere about this puzzle, but I can't find it right now.
Why did the vector cross the road?
It wanted to be normal.

There is a very nice explanation!
Sorry, I don't kow how to put direct link.

actually, the "triangle" is actually a quadrillateral, and the second diagram, ignoring the "missing" square, is a four sided figure, except that one of the angles looks like a straight line. the two triangles are not similar.
I shall be on leave until I say so...
