Lol. If you're standing on the North Pole, there's no east or west. There's just south.I still don't entirely grasp how East and West function at the poles either. Do they become curved along the lines of latitude or is there a sort of 'True East/West' perpendicular to the Earth's axis? I assume it's the former, so why would a triangle apply at all?
Goddamn it, I need diagrams for this shit. I'm a visual thinker.
--The guy's starting point is 5 miles away from the North Pole. Since everything on Earth is south of the North Pole, that means he is located 5 miles south of the North Pole.
--The first leg of the triangle: He walks 5 miles east, which still leaves him 5 miles south of the North Pole. (Basically, on the first leg of the triangle he is circling around the North Pole at a distance of 5 miles.)
--The second leg of the triangle: Then he walks 5 miles north, which puts him directly on the Pole.
--The third leg of the triangle: Then he walks 5 miles back to his starting point.
Trace it in pencil on a globe or a large ball or something.
