How do they move from wherever they die to the general poop area?

You know how people outside the USA vote? They go their, show their ID, get a tick on the list of voters, and do the voting.

So the picture is wrong then, the marked angle is top right (and the right angle, of course), the other angle is not marked, so adjacent and opposite are swapped.

How do you know which one is “opposite” and adjacent? They could literally be exactly the same but in any case they both touch the hypotenuse?

Happened before in general? Or specially to me? Everything as is exactly everything or just general things (getting up, working, …)?

So many options that mean entirely different things.
