Hi all

 

I've come across this pic and have been trying to work out how this is possible?

I dont know anything about geometry so i'm hoping that someone could explain this to me.

Any info would be greatly apreciated.

 

Cheers

 

Nevermind

 

I see there is already a thread on this

I guess it is from the sizes of some cells are different from that of others. As you can see, the hypotenuse of the top triangle is different from that ot the bottom triangle, indicating the cells are not uniform in size.

Is it right?

For the benefit of those too lazy to check the other thread with this problem:

 

The green and red triangles are not actually similar. The gradients of their hypotenuses are different - 3/8 and 2/5. Thus neither of the two complete triangles actually has a straight hypotenuse. The one with the filled square has an inward bulge, and the one with the missing square has an outward bulge.

I have the solution to this puzzle with the strigth lines drawn in. Its on my webiste:

Enjoy!
