Right Angles
Optical-Illusion
An optical illusion is a visually perceived image that is deceptive or misleading.Optical-Illusion
How many right angles appear in the following image?
You may see a cube, but the image actually contains three diamonds without any right angles.

yay first comment! It was ok...not one of the best, though...
Fun!!
cool
yea kewl
pretty cool! :wink
whoops i didnt mean to actually rite out "wink"
For a second there I could swear that those inner most angles were right angles.. that's a very cool spacial perception trick
good one
I hope someone works out a way to display "answers" to optical teasers that doesn't spoil them for fast readers. If you displayed the image first, we could shrink our windows and scroll down to the answer after we've had a moment to ponder.
Pretty easy!
ooooohhhh...cool...weird....
great angles
13 angles! cool
it kinda does have right angles....but if u say it doesnt...learn ur angles!
I di not like it as much as the others but good!!!!!!!!!
All of the optical illusions were pretty cool, liked the one with the glasses and dumbell.
I din't understand this one ... but don't have quite a keen eye for geometric optical illusions.
i agree with stil
This is one of those with a play on angles. Liked it. I agree with Stil in some regards, the answers should be down the screen farther so you have a chance to ponder the answer for just a second
it was cool like me
it was cool like me
it was cool like me
Im sorry i HAVE to say something about YnG18's comment that says
" it kinda does have right angles....but if u say it doesnt...learn ur angles!"
a right angle is a 90degree angle.. and none of those angles are 90 degrees, they are all obtuse and acute. (and incase you dont know what that means Obstuse = an angle greater than 90 degrees and acute = an angle less than 90 degrees).
And on a site note to poster of this Optical allusion. Diamond is not a mathematical term. The correct term is parallelogram

weird and really cool i never would have guessed
o ya and i agree with Morte 619...right about the acute and obtuse
sorry to say but i knew at once they were not right angles... had a maths test today on circles
Morte 619 said "Diamond is not a mathematical term. The correct term is parallelogram".
This is not neccesarily true, a 'diamond' could also be a rhombus if all sides were of equal length.

well, in response to the teaser - clever, but mildly disappointing in that its pretty much a given that 3D objects represented in 2d may be skewed, this one just makes sure all angles are skewed. as for others - even if diamond isnt a technical term (rhombus may be the one youre *thinking* of), it certainly is not... trapezoid may fit (didn't measure that closely) or just quadrilateral. good tries though
I don;t get it...
wait... now i do
That Rocks!!!!
It looks like squares
But when you look closer the magic unfolds

its called drawing w/ perspective....not too hard i learned it in art I....its not the best optical illusion i've seen but not too bad!!!!!
This IS just an amazing trick to the eye, and a totally amazing illusion, Jake! WTG
OMG!! Morte_619, talk about having to be all technical!! Yes, you are right about the acute and abtuse, but come on!! The diagonal thing is going a little far.
Ok - I know that the whole "not a diamond" thing has been cleared up, so I'm a little late. But reffering to them as diamonds was a little confusing cause I always thought that a diamond (shape) was just a square that was turned around meaning that the angles would be right angles (I know they're not!). Not my favourite optical illusion.
i liked it
Woah...
Pffft..
If you wanna get technical about it then FINE.

ummm it does look like it has right angles.....=|
*YAAAAAAAWN* you call that an ILLUSION? i learned that in 3rd grade!!!
i think it does have right angles if u look relly closely at it
why was the answer right beneath the question?? That totally ruined it for me.
i don't see it
I see it both ways. Neat!
hmmm... I don't see it.
why be so matematical? It's just an illusoin! By the way, is matematical a word?

oops! I didn't mean to write that out twice!
geeeees i see nothing but right angles
Like someone said earlier, this is just a disappointing trick question. Of course those aren't right angles. That's obvious. The perspective implies whoever drew it was trying to make a 3D rendering of a cube which has right angles. Nothing special.
About the parallelogram/rhombus thing.
Parallelograms are the generalized forms of a lot of quadrilaterals, rhombuses, rectangles, squares.
By saying that it should be rhombuses, you're not contradicting the former, since a rhombus is a specialized paralleogram

i agree with...the person who has just #'s...why be so mathmatical?!
and yes that is a word! LOL!
and yes that is a word! LOL!
Wow, cool!
love it
I don't know about anyone else but thats how i was taught to draw cubes in school. so i really don't see anything special with this one; as it's a cube drawn at an angle.
I don't get it. I don't see any diamonds.
You won't see diamonds because this is not a true optical illusion, or a mathematical diagram - it is a cube drawn at an angle. Disappointing and misleading
I love the optical illusions set, but I'm not sure this is one. I suppose if I were asked, "How many right angles are represented?" that would be a different question than, "How many right angles appear?" And of course people often answer the questions they think the questioner wants to ask as opposed to the question literally being asked. Still I am enjoying this series.
as far as i know, there is no carbon on my screen.
this was ok i seen better
This is really weird.

That was an ok Illusion. I have seen better. But good job! Very Creative! Keep em comin!
Hey dude, I made this today! *shows poster* Hey cool, a cube.
ITS NOT A CUBE, ITS THREE DIAMO- Hey wait, it does look like a cube...
Nice OI

Great trick teaser. I can see it now!!!!

I can see why you had 2 bad karma

awwwwwsome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Holo's comment cracked me up!!! But really, it's just an illusion! It's for FUN! You don't have to get all technical about it. The illusion is that it looks like a cube, which has all right angles. But since it's drawn like that, it is actually three diam-oh, wait, sorry, RHOMBUSES, that have no right angles. OK? You don't have to obsess over every detail someone got wrong!
Also, I just realized that my username is Candi7, and my comment is right under someone called Mandy7! Weird coincidence!
Holo... Lol
Well if we're going to get technical, I actually see a diamond and 2 rhombuses.
They are still angles, around... 140 degrees!
