Spherical ellipses and equilateral spherical triangles

open access: yesSpherical ellipses and equilateral spherical triangles
For a spherical triangle ABC such that AC ̸= BC on a sphere, the circular arc(ACB and the spherical ellipse on the sphere with foci A,B that passes through C intersect in exactly two points, and the two curves cross each other at the intersection points. This fact is applied to show extremal properties for equilateral spherical triangles.
