Question

in spherical geometry parallel lines intersect at ___










choices; 0, 1,2,3,4,6,8

Answer 1

In spherical geometry, parallel lines do not exist in the same way they do in Euclidean geometry. Instead, all great circles (the equivalent of "lines" in spherical geometry) eventually intersect at two points. Therefore, the answer to the question is that parallel lines intersect at **2 points**.
