Antipodal Points
Two points are antipodal (i.e., each is the Antipode of the other) if they are diametrically opposite. Examples includeendpoints of a Line Segment, or poles of a Sphere. Given a point on a Sphere with Latitude
and Longitude 
, the antipodal point has Latitude 
and Longitude 
(where the sign is taken so that the result is between 
and 
).
