Does no one understand this is a joke, talking about parallel lines and mathematical proofs is pointless when its a fucking meme

Its wrong though so the joke falls flat
Didn't realize jokes have to be literally correct
Just the good ones.
We do understand it's a meme and a joke. Just not a very good one, because one can easily poke holes into it.

That's not how jokes work.

These are parallel too. They just look that way because they are project on to the euclidean plain.

ITT: math people going "listen here you little shit"
A square must also have two pairs of parallel sides.
Calculus can find you two pairs of parallel sides, right there on the circle!

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:
- 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.
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.

Dammit Diogenes, this is why we don't allow you in the geometry class anymore.
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!".
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.
Learned this one in 6th grade geometry: drawing a square in thr corner doesn't make it 90°
But these are all right angles, as long as the two arcs are centered on the same point as the intersection of the two straight lines.
