In my culture, rhombus is the basis of a vagina pictogram. In my culture, rhombus is every schoolboy's favorite shape.

A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.

This is amazing and thank you for sharing. The ability of the human race to come up with different yet universally understood yonic symbols is heartening. Like no matter what place or time, we're all in this together and we will be drawing genitalia.
Hell my dude there's a cave people deliberately carved to look like a vag and it's incredibly detailed.
Humans just seem to love genitals to an alarming but understandable degree

Every square you ever met is a rhombus that gave up its art career and got a boring 9-5.
All shapes will be hunted down to extinction until the one and only remains.
Looked around my room
Stacks of books
Rectangular posters with rectangles on them
Windows, curtains, television
Then i saw the plaid shorts i am wearing and had a good laugh

Yeah, it's pretty good. But it's not a hexagon, which is the bestagon...

Wait until they find out it's all actually triangles
The only thing that's greater than humanity's obsession with rectangles, is computers' obsession with triangles.

This person hasn't done math past elementary.
I went up to Calculus I in college (along with some physics and engineering), and I've done a bit of amateur math outside of school ... but the concept of a rhombus was still used exactly zero times.
The engineers prefer triangles, the physicists prefer circles, and the pure mathematicians are usually dealing with weird shapes that don't even have names. Who uses the rhombus?
Right there with you, I didn't use it in analytical geometry, calcs 1-3, diff eqs, or numerical methods. I don't think it would have shown up in my other math classes either. I'm pretty sure the rhombus is nothing more than a happy shape.

This is true for most parallelograms and later polygons.
Daughter just went through parts of middle school that seemed to focus on things like rhombuses and trapezoids. The only thing I"m thinking, as an engineer, is when was the last time I gave af about any of those shapes? I would just reduce them to triangles and rectangles.
Trig skills are WAY more useful than knowing how to calculate specific polygon shapes..... I don't mean to say that middle schoolers should be learning trig... just that the time spent learning how to do specific shapes is a literal waste of time that they could be using to prepare for later things (like trig).
As someone in education i would bet money that since it is a vocabulary word with a simple definition in a subject that is hard to teach, it is included to make things easier on the teachers and students. Mind you easier isnt often a good thing, and in this case I'd say its lazy and irresponsible to focus on things that don't scaffold well or have much practical use

A rhombus is just an equilateral parallelogram, and parallelograms are the easiest way to approach vector cross products. And you're 3/4 of the way there when you do tip-to-tail vector addition. They should have come up at least a couple times in geometry. Rhombi pop up as faces in lots of polyhedra, and tiles in lattices. I don't know much about crystallography, but I'm sure they make an appearance.

They're not really mentioned in more advanced math. It's all polygons.
Ok, triangles are often treated as a special case. But for anything else it's a n-sided polygon.

ILLUMINATI CONFIRMED!!1!one!!
Isn't a rhombus just what you call a diamond that's having a bad day?
If I ever have my own home, my house will have a rhombus room.
"Don't you mean a rumpus room?"
Bro, that's not even a real shape.
Some pretty rhombus logic if you ask me
clearly you didn't learn, since diamonds are a pretty common shape
RhombusEvery 3 ft square box that you shoved a bunch of 3.25 ft long irregularly shaped items into then closed the flaps on is a rhombus.
Haven't you guys used a kite before?
A rhombus, otherwise known as a diamond. Its one of the more popular shapes past star, triangle, circle, and square.

Take a square. Lean it to the side. Rhombus. Take a diamond, let it fall on one of its sides. Rhombus. The world just keeps a-rhombusin, you just stopped a-noticin'

oh they don't appear again, but its generalization, the parallelepiped, does:
it's used to calculate volumes of curved objects. basically you chop down the object into a lot of small parallelepipeds (mentally), and then calculate the volume of each of them small things and sum over them. Done.
to calculate the volume of a parallelepipede, there's a surprisingly simple mathematical formula. If you have the vectors for the three sides a, b, c, then the volume V = (a × b) · c, where × is the cross product and · is the dot product. it's very simple and an effective way to calculate volumes of curved / deformed objects.

When I played "Psychonauts: In the Rhombus of Ruin" I got reminded again that this thing actually exists.
Rhombuses are really commonly used in trigonometry puzzles. You know, "Here's a bunch of lines and a couple of angles, find the angle at X."
You know what they say, all busses go to Rhome
It's also called diamond or zoomie square. You know, cuz it's like a square that's going so fast the pointy parts start at the tippy top
Imagine living as a farmer in medieval Europe near a small village and you make MOST of your shit yourself or with help from the local blacksmith. You'd use all kinds of things and ideas that we don't use any more. You need to be creative to solve your daily problems and find ways to do stuff efficiently. Like imagine you'd need to dig out a bit of earth for an "almost square" and need to calculate the area and volume of earth you'll have to move.
I'm not sure what I'm trying to say, but I think modern education is wasted on the modern human.

The word "rhomboidal" exists and you are allowed to use it as much as you like
