Magic Triangles

[DrSzin]

This magic triangle puzzle (http://www.tummyfluff.co.uk/puzzles/triangle.htm) is kinda neat. It had a couple of us bamboozled for a while. Unfortunately, my colleague figured it out first and he told me what the answer was, so I didna get to figure it out for myself.

There are lots more here (http://www.tummyfluff.co.uk/puzzles/index.htm). Some are really neat.

Not to sure about the triangles but there is loads of interesting stuff on there.

Aha! Got it (I think). Am I allowed to say yet?

The answer lies with the red and green triangles. Look carefully

[daviddd]

got it!

Took two seconds to work it out, and a quick check confirmed my suspicion, not so much an optical illusion as playing on our inability to compare two objects to such a degree of accuracy...

Well, I spotted the bit that "doesn't look quite right" straight away, but I was too dumb to follow it through quantitatively. :eyes

Maybe I shoulda thought about all that "useless" stuff on similar triangles they made us do in Maths at THS many moons ago. I never was any good at applying that sort of thing...

I've been staring at one of the other illusions for hours but I still can't see a boat in the background. Must go take another look. :confused

I thought it was a waterfall not a boat.
