ah yes, ignoring that is actuality 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 things fit a definition when you just ignore parts of it.

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.

en.m.wikipedia.org/wiki/Right_angle

Right angles must be comprised of two straight lines.

Right angle - Wikipedia

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.
    something tells me neither of these are genuine attempts at properly using the definitions but rather clever subversions in pursuit of… checks notes… humor.
    Let me introduce you to the Non-Euclidean surfaces to bend your concept of straight lines
    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.

    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?
    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.
    This is not a parallelogram and is therefore not a square
