I’m not a math major, but I always considered it that a square is a special case of rectangle, a rectangle is a special case of parallelogram, and a parallelogram a special case of a quadrilateral, a quadrilateral a special case of a simple polygon.
This shape isn’t a polygon, so it cannot be a square.
Oh let’s get pedantic!
The curved edges technically have infinite “side”.
…and a square has four interior 90 degree angles.
…and based on the infinite number of sides for a curved line aspect, the “90 degree” angles would all be +/- the limit as it approaches zero, so never truly 90 degrees but always an infinite fraction away.
the angles are interior if you go into the scary world of high level maths and their weird fucking geometries.
this is a square, from a certain point of view
Someone knows more calculus than they are letting on…
Hey, I failed the highest level of calculus possible. Twice.
I’ll have you know that I passed the two lowest levels of calculus required for my degree. So you know, I’m something of an expert.
Yeah, we gonna need more rigor on this one.
“A square is a shape made up of four equally long lines a, b, c, d where a is perpendicular to c and d and parallel to b. Each of these lines meet exactly two other lines at it’s ends.”
I’m not a mathematician so there might an odd case somewhere in there. Maybe it has to be confined to a shared plane?
Lines are infinitely long… do you mean line segments?
Wikipedia has a good enough definition: “It has four straight sides of equal length and four equal angles.” Nice and simple.
Pentagon fits that definition also since it doesn’t specify “it has four and only four” sides

So you’re saying this is the outline of a square in the astral plane? Because it sounds like you’re saying this is a square in the astral plane.
No, just a 2d plane
Hey, that’s my job!
Also I don’t think that’s technically the technical classification. I think that sidedness is an attribute that simply doesnt apply to curves.
You can approximate curves with some number of sides, and the approximation gets more accurate as the number approaches infinity, but it doesn’t actually have the infinite sides.Very cool! I’m always happy to learn something new!
I mean, I’m just pedantic; double check with a mathematician, to be sure lol
I’m genuinely curious, what is your job that requires arithmetic?
I feel like most jobs require arithmetic.
But it is not my career to be a pedant, just my role in life 😜Fair
Not if this square is a projection of a curved surface
If it is a projection, then there are more than two curved sides, which also begs credence to the interpretability of the angles they intersect.
Rotate the cone towards you.
Now you see this. 🤯
uhhh, wait. Under what projection is OP’s “square” reduced to an actual square
It’s possible, but there needs to be a thickness in addition to the length and width.
Im gonna need more than that as an explanation. Sandwiches too if you’re making some
Imagine you have a cookie cutter in that shape. Cut a cookie as thick as the chord of the largest arc.
View the new vertical surface of the longest arc that is now a cylindrical section.
Viola, square. 😁
*munches thoughtfully*
this is terrible, but it tastes okay
Science bitch
Straight lines. Also two sets of parallel lines. This is one definition of a square, but not the common one.
I believe these lines are straight with a black hole at the centre.
straight, gay, lines are lines. let them be.
If that’s so, the angles are probably not right angles.
None of the angles looks wrong either
Can straight be defined in a nonlinear environment?
I would guess on a sphere these can be straight yes: The pole goes into the center of cicular thing and radius of the sphere needs to put the other arc on one latitude.
Euclid’s first postulate: Give two points, there exists exactly one straight line that includes both of them.
Counterexample: North and Southpole on Earth.
No, it’s still accurate - the straight line goes through the center of the Earth. Only in coordinate systems where ‘straight’ is defined as following the curvature of a surface are there infinite lines between the North and South Poles… and that would be non-Euclidean geometry.
This only applies in 2nd order real space. Euclidean geometry aside, I agree with at least one line could exist between two points
Not a polygon

Plus the table.
Peperoni are bell peppers. I have no idea why the USA chose to use this word to mean salami, instead of, you know, salami.
You’re thinking of peperoncino, a spiced chilli pepper also known as sweet Italian peppers. We still have salami in the US.
I’d guess pepperoni is called that because it’s dried salami with pepper seasoning.
I found a link just randomly googling. https://www.thoughtco.com/you-say-pepperoni-3972377
Pepperoni and salami are totally different dude, you might as well be saying that Americans should just call their potatoes “yams”. And you can get both of those sausages and many, many more on your pizza, often at the same time
Listen if they put a pepperoni in the center of the pie then a poor cut is clearly the least of our concerns
Always put a pepperoni in the exact middle. It’s like a wishbone, but for pizza. The person who gets the majority of the center pepperoni gets a wish.
A center pepperoni is asking for the center of your pie to be fucked up
The interior angles need to be equal 🤓
Here you can see how things go haywire when skipping minor parts of definitions.

Someone never had to deal with mathematical proofs, only layman’s definitions.
All properties of a parallelogram apply:
- Opposite sides are parallel
- Opposite sides are congruent
- Opposite angles are congruent
- Consecutive angles are supplementary
- Diagonals bisect each other
AND
- All angles are congruent
- All sides are congruent
- Diagonals are congruent
- Diagonals are perpendicular
- Diagonals bisect opposite angles
Of course, but such strict definitions only come about because smart people come up with examples like OP when you don’t add the full definition.
Don’t the internal angles need to be 90°? Two of those right angles aren’t right angles on the inside.

Tut tut, all these maths books promoting unhealthy square shapes, real squares have curves.
Does no one understand this is a joke, talking about parallel lines and mathematical proofs is pointless when its a fucking meme
It’s not pointless because you can laugh about a joke and then learn something about math.
They don’t cancel each other out. They can be at the same place and still work on their own.
I love memes that are funny on their own, but also provide discussion material.
These are parallel too. They just look that way because they are project on to the euclidean plain.
Or the fun part.
Its wrong though so the joke falls flat
Didn’t realize jokes have to be literally correct
You’re having fun wrong!!1one
We do understand it’s a meme and a joke. Just not a very good one, because one can easily poke holes into it.
Just not a very good one, because one can easily poke holes into it.
That’s not how jokes work.
Depends on the joke.
No, it depends on if you have humor. Yes, humor is individual, I know. But people without tend to over analyze and try to pick the joke apart, often missing the point.
A joke doesn’t have to pass every technicality. You thinking it’s bad if it doesn’t, only applies to your humor (or lack there of).
Ooh, watch out, the humor police is here! Everything the deem funny is humor and if you don’t find funny what they do you don’t even have humor! Wee-ooo wee-ooo!
Its supposed to be absurd, taking it seriously makes the already bad joke even worse
It’s not about taking it seriously. The meme wants to be a technically correct-meme, where a thing fulfills another things definition and thereby could be deemed the other thing - which creates the absurdity the meme lives off of. But in order for that kind of humour, there cannot be obvious holes in the logic of the joke and these obvious holes are very present in this meme.
Any maths joke of this type will have obvious holes in it, that’s just how maths works
