It depends on what the name of the initial point is because that defines the direction of the ray. If the initial point is c, then the ray must be called cd, but if the initial point is d, then the ray must be called dc.

A ray has only one end point.

The origin.
The ENDPOINT
There is no end point, a ray is never ending but has a point to represent the beginning
a ray is (any of the thin lines, or beams, of light that appears from a bright source)
The initial boiling point is the temperature whereby the first drop of distillate has appeared.
a ray starts at a point and goes on forever
The initial boiling point is the temperature whereby the first drop of distillate has appeared.
The point at the end of a ray is called the endpoint. It is the specific location where the ray ends or terminates.
A ray has only one end point.
Between the initial point and the final point.
