Optical Illusions

[Noxide]

Hey dead_man can you explain this?

Yes but the red triangle takes up 3 lines in height, whereas the green one only takes up 2.

Meaning the light green and yellow/orange pieces won't fit under the red triangle without making the entire triangle bigger.

The yellow and light green blocks has to be re arranged in order to fit in the image.

i'm confused now...so what's the correct answer?

I think

The hypotenuse is not straight!

The top triangle has a sliver of a tuck and the bottom triangle has a slight bulge.

ok ?

And

Optical illusion… read the words between the blocks. If you can’t read it, just get off your chair and try reading it a metre (or two) away from the screen.

Maybe gerrit is right.


If you cut the first figure and put on the second one, you can see the thing:

oh in that triangle illusion, the hypotenuse (slanted side) shifts a little, "creating" the hole. I plotted it in autocad.
