WebAug 11, 2024 · 1. The longitudes are great circles, and they meet the equator at right angles. In this case we would say that one line (the equator) can have infinitely many perpendicular lines. But of course two of those perpendiculars need not be (and cannot be) parallel in spherical geometry. – hardmath. In mathematics, a great circle or orthodrome is the circular intersection of a sphere and a plane passing through the sphere's center point. Any arc of a great circle is a geodesic of the sphere, so that great circles in spherical geometry are the natural analog of straight lines in Euclidean space. For any pair of distinct … See more To prove that the minor arc of a great circle is the shortest path connecting two points on the surface of a sphere, one can apply calculus of variations to it.
