You need to learn yourself some molecular geometry. An octahedral molecule forms a perfect right angle due to its bonds. Sulfur Hexafloride (SF6) is one of those molecules. So yes, nature makes perfect right angles.
Are we talking “in a lab”, or “in nature”. Because I may not have studied molecular geometry, but I know a lot about metallurgy. And “in nature”, every compound contains impurities.
I’ve never drawn a “perfect” square…and neither has anyone else. There will always be some deviation from a perfect 90 degree angle, except in theory. Even if that deviation is infinitesimally small, it still exists when an angle is measured accurately.
That’s what defines a right angle. When one line stands against another line, so that the angles on either side of the first line are equal, or “right” to each other. In mathematical terms those angles would have to both be exactly 90 degrees in order to be “equal”. Even the slightest difference between them, and they are not considered “right” angles anymore.
This is why the meme above says, “My science teacher: right angles don’t exist in nature”. Because no naturally occurring structures are exactly 90 degrees. Ever. There is always some tiny variance that breaks that theoretical requirement.
The person I responded to said, “I doubt very many science teachers would have said that”, but they do. At least at more advanced levels. It’s a common teaching parable that opens the conversation about the inherent “fuzziness” of reality. Even the most accurate measurements will always have a certain amount of baked-in uncertainty.
Reality itself is messy. There are no true right angles. No perfectly parallel lines. No truly flat surfaces. The best you can ever do is get ridiculously close.
So, when you measure a right angle in physical chemistry, you get exactly 90 deg with zero decimal points? That’s amazing.
And also impossible. There’s always a variance.

This distinction is meaningless for the purpose of this conversation
They said octahedral molecules, those are common enough that I think you find several kinds of them in mineral water.
Compounds are not molecules
A quare is defined as having four right angles. By your definition of right angle, you’ve never drawn a square in your life.
Stop being a pedant and admit that you learned something today.

You are the one who brought up “perfect”. That’s not even the claim in the OP, so I’m not clear what point you even think you are making.
