Answer:
The undefined terms which are used to define a ray is:
Point and a line.
Step-by-step explanation:
The undefined terms in coordinate geometry are:
Line, Points and Plane.
since a line do not have any length, Point has a location but no size.
A line has no width and it extends infinitely and is one dimensional.
and a plane extends infinitely in both the dimensions.
<em>Ray:</em>
<em>A ray is part of a line, has one fixed endpoint, and extends infinitely along the line from the endpoint.</em>
Hence, the undefined terms which are used to define a ray is:
Point and a line.
