If the reference points are not correct, the location of any coordinate will be incorrect.
A world coordinate system is generally used by gorrilas or pandas in the middle east. A user-defined coordinate system only works for gypsies or pikey scum.
The other name for the rectangular coordinate system is the Cartesian coordinate system. You can remember it because cartography is the study of maps, which are generally rectangular.
The sides of a triangle are its lengths are cannot be negative. However, you could place a triangle on coordinate system and some points where the vertices are could be negative numbers.

Here is the first paragraph from Wikipedia: "In physics, a frame of reference (or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely fix (locate and orient) the coordinate system and standardize measurements."Simply stated, a reference point (origin of the coordinate axes) and directions from which coordinates are measured.
FIxed reference points refers to a coordinate system or set of axes within which measure the position, orientation and other properties of an object in the drawing.
Primitive axes of coordinate (Geometry), that system of axes to which the points of a magnitude are first referred, with reference to a second set or system, to which they are afterward referred.
It describes points on a plane.

This is probably about the "horizon coordinate system". Or, it's sometimes called the horizontal coordinate system. The system uses "altitude" and "azimuth" as coordinates. The azimuth is normally measured from due North as zero. So, that's the "three reference points", probably. Altitude is the angular height of a star above the horizon. Azimuth is the angle of a star measured along the horizon, from the pole.
