Lines that intersect a circle like that aren't "right angles" tho, they're called "normal" to the circle - in other words pointing directly toward the center. A normal line is at right angles to a tangent line, but not to a curve.
Don't the internal angles need to be 90°? Two of those right angles aren't right angles on the inside.
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.
Not a polygon
Oh let's get pedantic!
The curved edges technically have infinite "side".
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
....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

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. 😁
The interior angles need to be equal 🤓
Here you can see how things go haywire when skipping minor parts of definitions.
Straight lines. Also two sets of parallel lines. This is one definition of a square, but not the common one.

Diogenes go home.
Wrong. This is a definition of a [pizza] + [the extra peperoni from the other slices that got stuck to that slice because the cutting was imperfect]

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

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.

ITT: math people going "listen here you little shit"
Tut tut, all these maths books promoting unhealthy square shapes, real squares have curves.
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.
