ah yes, ignoring that it should actuality be a polygon, implying a closed shape with straight sides much like this ignores the "weapon" and "used for thrusting or striking" parts of the definition.
not hard to make strange things fit a definition when you just ignore parts of it.
something tells me neither of these are genuine attempts at properly using the definitions but rather clever subversions with deliberately obtuse interpretations in pursuit of... checks notes... humor.
Let me introduce you to the Non-Euclidean surfaces to bend your concept of straight lines
Relax, take a deep breath<3
No. You can't just put little boxes in the corner and call them right angles THERE ARE RULES WE LIVE IN A SOCIETY
But that's correct in the image there - they are perpendicular or as you in the US call it "level", they are all 90° and pweze pweze don't forget you're trying to be pedantic in a comments section of a stolen meme in a community called shitposting like just chill c:
It's not pedantry, you just don't know elementary level geometry.
https://en.m.wikipedia.org/wiki/Right_angle
Right angles must be comprised of two straight lines, and by also by similar definition a curved line can't be perpendicular to fucking anything.
That angle can be 90 degrees at the point of intersection because of how angles in this case are measured but it is not a right angle or perpendicular. This why the definition of right angle is more complex than "a 90 degree angle."
pedantic/pə-dăn′tĭk/
adjective
Characterized by a narrow, often ostentatious concern for academic knowledge and formal rules.
"a pedantic attention to details."
You are very much correct in the fact that angles by definition are only present between straight lines. A secant line that is in the same plane as the circle and is crossing the centre of the circle is called it's normal and a normal is by definition perpendicular. The meme was fun
It's not pedantry, you're just offensively ignorant.
The idea isn't literal, it's to show that our language is entirely just noises that we've made into increasingly complicated levels of agreed-upon abstraction. We don't mine words out of the Earth, we develop them to create clear explanations that we can all agree on, and yes, the more you peel away or dig in, the more challenging it can be to create words that encompass all variations of an idea.
This image makes me angrier than it should. Those 4 "right angle" designations are all lies. You cannot have a curved line attached to anything and call it a "right angle". It's not. Like, factually. I don't care if it's 2 feet long, or 200,000 miles, it will never be exactly 90°, which invalidates the entire thing.
If it’s not a right angle, then what is it? Wouldn’t you just measure the angle between the tangent of the curve and the line? Working with the tangents is how you find the angle between two curves as far as I know. You say it will never be exactly 90 degrees, but it would be 90 degrees at exactly that point. That’s not a weird thing to say from a math perspective.
I think a bigger issue with this figure is that they’re using some internal and external angles for their count of 90 degree angles. (And that this is just a ridiculous twist on a square, lol.)
OK. Walk in a straight line for a couple of metres and stop. Rotate left or right by exactly 90°. Now take a curved path in any direction.
Did you or did you not turn 90°?
That doesn't make the resultant diagram 90° at those vertices. That's just empiricist stupidity.
OK, then what angle is it?
This is not a parallelogram and is therefore not a square
