Earth's two fixed reference points are the North Pole and the South Pole. These poles serve as the primary geographic markers for defining latitude, with the Equator located equidistantly between them at 0 degrees latitude. They help establish a coordinate system for navigation and mapping, allowing for consistent location referencing across the globe.
It is a line segment.
I believe that is the definition of a straight line.
It is the locus of points such that the sum of their distance from two distinct fixed points is a constant.
The two fixed points are the foci but these do not define the shape of the ellipse. You also need to know the eccentricity.

Two nonmoving objects that are useful reference points are a stationary pole or a fixed building. These objects can serve as points of comparison or markers to determine direction, distance, or positioning.
We have several reference points on the Earth's surface, for our convenience. The North and South Poles are a couple. The choice of Greenwich as the zero longitude, and of the International Date Line are another two. These points have no specific feature on the surface, they are decided on for the convenience of the users.
The two basic points of reference on the surface of the Earth are the North Pole and the South Pole. These points represent the northernmost and southernmost points on Earth's axis of rotation, respectively.

The Celsius scale is based on two fixed points: The freezing point of water at 0 degrees, and the boiling point of water at 100 degrees.
They are North Pole and South Pole
In Euclidian or plane geometry, there can be only one line through two fixed points. Lines cannot actually be drawn; if you see it it is not a geometric line. If the points are on a curved surface as in a geometry that is non-Euclidian, then there can be infinitely many lines connecting two points.
