For a second there I could swear that those inner most angles were right angles.. that's a very cool spacial perception trick

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.

All of the optical illusions were pretty cool, liked the one with the glasses and dumbell.

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

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
Dishhead5Aau*
Aug 11, 2006

sorry to say but i knew at once they were not right angles... had a maths test today on circles
RiddlermanAen*

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

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

Jan 20, 2007

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 think it does have right angles if u look relly closely at it

geeeees i see nothing but right angles
UlsterCharlotteAus*
Jan 24, 2008

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 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.
elthamlass*
Nov 17, 2008

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

Dec 24, 2008

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.

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!
