Description of arcs
edit"If an arc is extended, it will form a great circle. A great circle, however is the end of the lines path".
I can think of two points drawn in the upper hemisphere of a sphere whose arc will not produce a great circle when extended. Is it implied that these points must be antipodal?
Also is that that supposed to be "line's path"? Kbkmoore (discuss • contribs) 13:15, 25 February 2023 (UTC)
