What a bunch of bullshit. Just draw it way off 90 if you don’t want people to use a protractor. I calculated 125° because of this (but I’m happy I still got the right wrong answer, if that makes sense)
In my geometry classes, it’s only 90 degrees if it’s marked by a right angle marker. Otherwise, no matter how “right” it looks, if you assume before proving, it’s on you.
this is a meme tho. i wanted to treat it like a “real life” problem where if i saw those obviously 90 degree corners, i would just say it’s 90 because nowhere else in all my life outside of stupid schoolwork trick questions would that happen. which meant i got to the answer in a few seconds, which is a handy skill in real life.
You could potentially run into this or something very similar in cad when your sketches aren’t fully defined yet. I’ve definitely ran into models that are slightly off square because someone missed a constraint much earlier in the timeline.
Yes I originally thought 90 but then noticed the absence of a right angle sign. Also 60+40=100 which means the last angle should be 80. Making that perpendicular 100/80
correct, just commenting the 100/80 intersection looks like 90/90, i think it was intentionally misleading, classic trying to get you problem

Its not bullshit, its conventions that make a lot more whole sense later on.
