A person starts at his hut, travels 2km south, then 2km east,
then 2km north and is then back at his hut. The expected answer is that the hut is at the North
Pole. However, the hut could also be in the southern hemisphere.
Which diagram represents possible sets of points near the South Pole?
(The correct answer has three circles in a square)
edits: in a square there's a circle, in the circle there's a circle with another circle in it.
Please explain to me. Thank you!
