It is at least according to this definition from
http://mathworld.wolfram.com/SphericalPolygon.html
"A closed geometric figure on the surface of a sphere which is formed by the
arcs of great circles. The spherical polygon is a generalization of the
spherical triangle.

I can't tell whether this is a puzzle for the list to enjoy puzzling over,
or whether it's something you want answered. I doubt that I'm spoiling
anyone's fun by suggesting that the answer is "lune".
Is a figure on the surface of a sphere properly called a polygon? I don't
know the answer, but would like to. Anyone?
