A square is a rectangle, but a rectangle isn't necessarily a square

Same with rhombus and diamond

A rhombus is a diamond, but a diamond isn't necessarily a rhombus

Rhombus has to have four equal sides, a diamond does not.

I think most people would say a 2D shape that they'd call a diamond would have 4 equal sides.

I don't think very many at all would call an elongated parallelogram a "diamond".

If I took a traditional diamond shape and elongated just the bottom sides.

I feel like most would call it a diamond still. Specific term would be a kite. Many wouldn't come up with that, though. It's not an elongated parallelogram. It is not a rhombus.

"Diamonds" on bicycle playing cards have curved edges. They are not a rhombus because sides are not parallel. Most agree that it's the classic diamond shape, though.

If you give someone paper and a pencil and ask them, "Please draw a diamond shape."

Most will draw a 4 sided shape with 4 equal sides.

People would definitely want to elongate the top and bottom sides because they do not want to draw a sideways square, which is a rhombus, parallelogram, diamond too.

There's no way a human is going to draw 4 equal lines

No one at the end is going to be like "yeah but you have to be sure all sides are equal" when they have some kind of weird kite shape.

There's people out there that wouldn't count a sideways square as a diamond

IDK why you think that "4 equal sides" is the same as "sideways square".

You can (and frequently do) have equal sided diamonds that aren't "sideways squares".

Seems like your main issue is geometry.

People would definitely want to elongate the top and bottom sides

Which is fine. As long as they elongate symmetrically (which most would do), they're still four equal sides.

There's no way a human is going to draw 4 equal lines

Yes they would. In fact most would, I'd wager.

Sounds like your concepts struggle is comprehending that "four equal sides" isn't the same as "four equal vertices".

There is no such thing as a diamond in geometry. The correct term is a rhombus.

That shape is a kite in geometry.

You ask 100 people what that shape is.

How many are going to say diamond?

Even the people that believe diamonds have all equal sides would say "It's not a perfect diamond but it is diamond shaped"

Imagine saying "It's not a perfect square, but it is square shaped" at a rectangle.

For me the shape I was thinking of was if you take a simplified 2D version of this 💎, with there being 4 sides, 2 pairs of equal sides but not 4 equal sides

I imagine what people are talking about here is this ♦️ sort of diamond.

I blame me not being a native speaker for thinking of diamon diamond

True, I didn't pay enough attention but I though the two upper sides touched each others at the top, so it would have just 4 sides

Unless you live in North Dakota, where the Rhombus Guys pizza chain is located. Pretty good pizza, though overpriced.

JFC, I just looked it up and I think the other guy is right. There are now 2 Dakotas somehow. What is the world coming to?!

Used to be we'd go there because they'd serve you a 10% IPA in a giant 32oz mug or whatever and charge you the same price as what JL Beers would for a 10oz of the same beer. It's been at least 6 years since I've been in either of those because they are just so crazy overpriced now. I also don't drink much anymore, but god damn that Lost Continent IPA was good.

CT resident, new haven style is burned badly, the toppings are distributed at random, and there's gigantic bubbles in the dough. You're an hour and a half from NYC, just get a good pizza and stop pretending pepes and Sally's aren't shit.

I like how these cities are convinced that nobody else anywhere in the world has figured out how to put dough, cheese, and marinara sauce together in the proper ratio.

I have had pizza in Chicago and New York and it was good, but there is good pizza everywhere I have lived in the US. As long as its a local place its normally pretty good. It's not that difficult to get right.

I've also had bad pizza in both Chicago and New York. There's a lot of idiots dying on that hill.

Edit: a word

There's a rhombus on my argyle sock There's a rhombus on my argyle sweater There's a rhombus, on that diamond back snake Rhombus, oh you'd better not pet her I saw a rhombus shaped kite flying up in the sky I saw a rhombus shaped marking on the head of a horse I saw a rhombus shaped sandwich at a fancy party And a rhombus shaped sign that said baby on board A rhombus is a diamond With all sides the same length BOT A: You can measure it You can ride a bus, but have you ever ridden rhombus? BOT A: This playing card has a diamond on it BOT B: I prefer to call it a rhombus BOT A: Go fish! See a rhombus on a jeweled crown Run a rhombus when you hit a home run With a rhombus you can draw a manta ray A rhombus is all kinds of fun! It's a rhombus BOT A: You look nice in that argyle sweater BOT B: Thank you. It was a gift from the horse.

Funny I just used it last night after having not used it since who knows when. Didn't want to say parallelogram.

Actually, it’s four really good points. Am I right ladies?

NGL that sounds like it would make a good swearword.

I'm sad they never watched Adventure Time.

I come across that word every now and then, just like most other words that are not super commonly used. I feel like people who say things like this don't interact much with anything outside of top-level mainstream media. They only know about and watch the most popular things, which are in general pretty dumb things. They only listen to whatever is the newest hit, only watch whatever AAA movie or series is currently being advertised everywhere, they don't read or engage in anything else.
