That's pretty cool. Similar to the 12 --> 13 people one that was posted.

The animation makes it difficult to see what is going on, if you look at this pic of the second diagram it helps you to see it better.

Basically, the diagram is not a true rectangle, you can see this by calculating the gradient of the long diagonal.

If you count horizontally from the bottom right hand corner, along the bottom until you come to the join: this is 8 squares. Then count up from there to the next join ; 3 squares, which gives a gradient of 3/8. Now count from there along to the edge which is 5 squares. From there up to the top is 2 squares. So the gradient of the long diagonal is 2/5. So the long diagonal has two different gradients. But a straight line only has one gradient, so the long diagonal is not a straight line. Problem solved.

the solution is harder than the problem

Sorry,but that one went past me. Math class was many years ago. It wasn't one of my strong subjects even then. Grab's expaination just made it worse.

i was just demonstrating that the part of the long diagonal from the bottom left hand corner to the square dot directly under the 8 has a gradient of 3/8. Also the part of the long diagonal from the dot under the 8 to the top right hand corner has a gradient of 2/5. It is a simple fact of maths that a straight line only has one gradient. The long diagonal has two different gradients so it is not a straight line.

well... I would agree on that with you but..... huh?
