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
Someone never had to deal with mathematical proofs, only layman's definitions.
All properties of a parallelogram apply:
AND
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.
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.
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.
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.
Its wrong though so the joke falls flat
Didn't realize jokes have to be literally correct
Just the good ones.
Or the fun part.
You're having fun wrong!!1one
These are parallel too. They just look that way because they are project on to the euclidean plain.
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.
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.
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.
A square must also have two pairs of parallel sides.
Calculus can find you two pairs of parallel sides, right there on the circle!
I get downvoted for bringing it up, but for fuck's sake you're dumping literally everything into this community regardless of the fit. There are a dozen (I'm estimating) other communities that could benefit from the content you post but you have thus far insisted on only posting here.
Can you at least make the tiniest effort to spread content to other communities that would benefit from the increased views and potential subscriptions?
I shall await the fun police and everything's a meme comments.
At least it's better than endless American politics.
I'm sure there are more than a dozen and you are right. I'm still trying to get the hang of the whole fediverse thing, but so far most of the more niche communities I have tried to interact with are on different servers not federating with each other? Or maybe I'm doing something wrong? Not sure about that one. Also not sure if cross-posting works. I mean I know it works, but do those posts federate correctly? Can other fediverse apps see them correctly?
Thank you for calling it out. Had a look at post history and I agree, blocked. Lemmy is attracting all sorts of random noise lately.
If it clucks likes a chicken and scratches like a chicken, it's Man.
I got that reference!
Behold, a featherless biped!
And for those who don't: Plato, a Greek philosopher, was putatively asked by a student while teaching at the Academy what the definition of a man (human) was. Plato responded that a man is a "featherless biped".
Diogenes, another Greek philosopher and infamous quick-wit, caught wind of this and thought that was the dumbest thing ever, so he gate-crashed one of Plato's lectures and pulled out a chicken which had all of its feathers plucked out and said "Behold, a man!".
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.
Solution:
Explanation:
in order for the straight lines to be 90 deg with the circles, they must be radii of circles with same central point
the length of an arc is defined as c = r * θ (where r is the radius, and θ is the angle)
we define the inner circle with radius r₁ and its arc L₁ = r₁ * θ₁
we define the outer circle with radius r₂ and its arc L₂ = r₂ * θ₂
Because of (1), θ₁ + θ₂ = 2π
To create the shape, L₁ = L₂ = r₂ - r₁
If you start replacing and solving, you will get a 2nd grade quadratic, which has a positive and a negative solution. The positive solution is that magic number.
Dammit Diogenes, this is why we don't allow you in the geometry class anymore.
Tut tut, all these maths books promoting unhealthy square shapes, real squares have curves.
Diogenes go home.
Thanks, I hate it.
