It is the same triangle. I just spent about half an hour drawing and cutting out the puzzle on cardboard. (I'll post the pictures soon) The puzzle is as shown. I am so confused!
http://home.earthlink.net/~toddwolly/vision/triangle.html Doh! it's a pretty amazing puzzle, had me really going..... It's so hard to see the difference!!!
No, the answer is that the bottom is a four sided shape really, it goes out slightly at the joint of the green and red triangle pieces creating a 'corner'.
The red triangle is 8 by 3 and the green triangle is 5 by 2 so they are 12 squares and 5 squares big respectively. The other two are 7 and 8 squares big. The area of all the pieces is therefore 32 squares.
A perfect 13 by 5 triangle shape would be 32.5 squares big. Neither of the pictures are perfect triangles. They are both 4 sided shapes.
The red 8 by 3 has a gradient on its diagonal of 2.666 The dark green 5 by 2 has a gradient of 2.5
In the top picture the diagonal is bent inwards so a half a square from a perfect triangle is above the line.
The diagonal line in the bottom picture has a peak creating an extra half a square in the "roof" so that there are 33 squares in that "triangle" and as there are only 32 in the assembled shapes - a gap.
Got two kiddies and a cat. Live in a flat in Brighton. Have many issues!! Used to be a tree protester and sell Big Issue. Still want to make a difference, will teach my kids to carry on. Still growing up and learning what its all about.

Not the same triangle - if you look closely the sloping edge is slightly higher on the bottom triangle. Only slightly, but it's enough.

I blame Tony Blair.
