Amazing illusion - How can this be true?

hmmmmmmmmmm!!!!!!!!!!

In the top figure the sides if the red and green sections that make up the hypotenuse are not lying on the same line. Ths composite line that makes up the hypotenuse of the triangle is not straight. When the pieces are reversed the line that is the hypotenuse becomes convex rather than concave the resultant difference in area is reflected by the missing piece in the bottom figure.

Very good analysis/explanation! : )

It's because the sum of the individual shapes is 32 squares yet the sum of the total area (5x13/2) is 32.5 squares...

hey!!! i was gonna say that!!

Wow!

Then you'd be as incorrect as he is...

Oh my god,
you are kidding op.

the answer is: only people who care for visual trivial games care.

FUCK

DUde is right...I stand corrected and appologize!!!

Am I missing something!? - it is not an optical illusion at all and there is nothing surprising about the rearrangement of the pieces.

I don't care about visual trivia games...... someone asked and I answered.

I dont think it's an optical illusion. There is something disturbing there:

For instance reverse the first triangle and you obtain a big rectangle 5 X 13.Maintain the initial hypothenus to keep the two big triangles separate.

Now consider reversing the small green triangle as well as the red one. For both, you obtain two equal triangles from on side to other along the hypothenus.

But what about the remaining areas ? 3 x 5 = 15 squares in one side and 2 x 6 =16 on the other side.

This is impossible according the Euclidian mathematics.

What do you think ?

That answer makes me feel even dumber than the original conundrum.

My, I think Anonymous Coward 237748 doth protest a little too much :)

SIMPLE:: Its not an exact strait line on the top side ! In one view it comes in slightly and on the other it goes out slightly! Like I always say Praise The Lamb: Amen hold a straight edge to both top lines !!Helps if you gave a flat screen! The top picture the red and darker green sag slightly in the center! In the bottom they rise in the meeting spot! They stay the same size but increase the total one square! Is that easy enough to understand! I just thought of a easy way to explain it , Think of a triangular cake mold . You put in twenty cups to fill it ! Now pull one side out a little and it will hold another 1/2 cup. Now push that same side in a little and now its one cup to full ! The pushing and pulling are barely seen but the change in batter is one cup :: Easy

Took me at least 3 seconds to figure that one out! Its just like looking at how evolutionist count time ! Their alway's crooked!

I do not agree with TRIVIAL criticism. I did not think the question was trivial....... I like cerebral exercise!, although it did not require much.

It's simple, really. The top red triagle is 8 boxes long and the bottom red triangle is only 7 boxes long. The red triangles are not the same size...

And so we digress.

LOL - Come on, admit it. Admitting it to yourself is the first step...

AC227358 - Count them again

What's so difficult about this?

The Red triangle has a 3 square side, permitting the Yellow and Green objects to join and form a contiguous geometrical form.

The Green triangle has a 2 square side. So the Yellow and Green objects cannot join like in the previous situation.

The only way to maintain the general triangle shape made up of all these units is to leave an empty space there.

Why wouldn't this be true? What's truth got to do with it anyway???

Acht du leibe zeit!

Ahhh..... GLP never ending amusment.
