Not logical is it.

Post by: DenBee on June 03, 2007, 10:38:11: As far as I can see looking at the gridlines, the second shape is occupying more space than the first, obviously because it's incorporating that extra square in the bottom line. Follow the top (hypoteneuse) line on the second triangle, and compare it with the same line on the first diagram. It doesn't follow exactly the same angle.

No doubt there's a proper technical explanation for this somewhere on t'web, but I'm definitely not a mathematician. :D

Post by: DenBee on June 03, 2007, 10:39:49: Actually, ignore that last post. It was all rubbish. It has to be the same angle, doesn't it, because it stops and starts in the same places. I dunno! :-\

It was resolved - 15th. March 2005.

Post by: emmy1978 on June 03, 2007, 21:53:06: Right, with Denbee that the top shape occupies more space but from there am lost but then maths and I are not friends.
Telboy - HOW?????

Title: Re: More a fun puzzle
Post by: kenkew on June 04, 2007, 13:35:18: Well, I don't see a difference in the angles. After printing and cutting it out and l;aying one on top the other, they still look the same.

Likewise, the bottom left point of the green triangle in the first picture.

The difference is only slight, but you can see it.

Post by: emmy1978 on June 04, 2007, 20:39:10: Yep. I hate maths. It is not my friend. ???
Title: Re: More a fun puzzle
Post by: kenkew on June 04, 2007, 21:35:48: I don't see the difference, but if there is one then OK. But enough difference to fill the empty square? Still not convinced.

Post by: Marymary on June 04, 2007, 21:37:31: I can't see it either.

Post by: Andy H on June 04, 2007, 22:03:33: Despite posting the link to the answer I find it hard to believe a whole square too :-\

Post by: DenBee on June 04, 2007, 22:16:06: So ner, Trixie, I was right. :P :-*

I even used the proper fancy words and everyfink. ;D

Course I didn't have the courage of my convictions. ::)

Yep, but still got my eyesight. :)

Post by: Belinda on June 08, 2007, 10:50:28: This has been driving me bonkers but I think I finally figured something out.

I drew the top outer triangle on graph paper showing millimetres with a fine pencil, then starting in the bottom right corner put in the other shapes, the bottom light green one 2cm tall on the right side, then the orange one above it 1 cm tall.

The top left corner of the orange shape does not in reality intersect with the angle of the outer triangle but sits 1mm below it. Given that the top green triangle is 5cm wide, that accounts for half of the 'empty' square in the bottom diagram.

Not sure where the other half comes from, maybe my fine pencil is not fine enough and there is actually a 2mm gap?
