an equilateral triangle
The relationship is one of identity. The number of lines of symmetry for any object, are always identically equal to the number of lines of symmetry for that same object.The relationship is one of identity.

Sphere
None. For a 3-dimensional object, a line of symmetry implies rotational symmetry and an aircraft has no line of rotational symmetry.
