I had one helluva time grasping this until a TA I had took three push pins and a length of twine. With these, she constructed a triangle on a globe of the earth, then handed me a protractor and invited me to measure the interior angles. Crystal clear, after that.

Amusing extremes of that: if you put the three pins on the pole, on the equator and another on the equator a quarter of its length away, you get a triangle with three right angles.
If you put all pins along the equator, you get a triangle with three 180 degree angles that's just a circle.
