The 22 pages that link to Great circle, each with the reason it gives.

• GeodesicBroader topic: Its arcs are the sphere's geodesics and give its locally shortest surface paths.

• SphereBroader topic: It is the largest circle that can lie on a spherical surface.

• Line (geometry)Broader topic: It is a spherical analogue of a straight line, not a Euclidean line.

• Spherical trigonometryBroader topic: Great-circle arcs form the sides whose lengths spherical-triangle formulas relate.

• Elliptic geometryBroader topic: Great circles represent lines in the spherical model of elliptic geometry.

• HemisphereBroader topic: A great circle can form the boundary between two hemispheres.

• Great-circle distanceBroader topic: Every shortest surface path between non-antipodal points follows an arc of a great circle.

• Spherical triangleBroader topic: Each side of a spherical triangle lies along a great circle.

• Spherical excessBroader topic: The sides of a spherical triangle lie along great-circle arcs.

• Unit sphereBroader topic: Great circles are the unit sphere's geodesics and have circumference 2π.
