On this grid are two triangles made up of several different colored pieces. The first triangle is complete, however the second triangle which appears to consist of all the same pieces as the first has a square missing. Where has it gone ? Try counting the blocks that make up each piece - are they the same ?

The area of the whole triangle is 32.5
the red triangle 12
the blue triangle 5
the green piece 8
the yellow piece 7
if you count them = 32 we mis a .5
I think the wrong in the lines

These are not triangles. They are quadrilaterals. If you look closely you will see that there is a slight angle in the hypotenuses of the "triangles" -- that is, there are actually four sides to the figure: the two obvious ones, and two for the long side. I think that that was what the foreign person was trying to say, just in clearer words.

You have to arrange the colors differently then it will all fit together and the whole thing will be perfect!!

its easy you just need to arrange the triangles differently DUH!!!!!! No one can say i'm wrong on this one.

They are not triangles, just measure the angles if you don't believe me. They are concave quadrilaterals or arrowheads if you like.

The reason is because of the way the colored shapes are aranged. I counted every colored square, and compared them. If you do the same, then you will see. Trust me. I am right on this one.

Its easy it all depends on how you place the triagles.
the diamater changes due to the fact some triangles perimeter may not all fit in a certain place.

they switched triangles... which might of allowed the orange block to shift, then create an illusion...
like that game "jelly blocks" (search it on google, or addicinting games)!

no illusion at all...

it look like an illusion but if you draw a line between
sharp angles o trianghle you will see that: the longest line from triangle in not a line is made from two line. Is more simple to make all shape from big paper and will see a little diference af angle.
sorry about my englesh but I hope you manage the ideea.

the bottom triangle is larger than the top triangle. each triangle are not triangles they both have 4 corners. look closely at each overall triangle/straight lines.

Copy the image
cut each piece out
slowly put them back together 1 by 1 to create the bottom image.
I makes me so angry
