In Euclidean geometry point, line and plane are not defined.
A set can be defined or undefined.
The three undefined terms are the point,the line and the plane.
A term that is undefined mean simply that it is not defined. The prefix un means not, and if you add it to the word defined, ta da, you get undefined.
A ray is not an undefined term.
Point is not an undefined term. It can be defined as a mathematically precise location, or as the place where two lines intersect.

In Euclidean geometry point, line and plane are not defined.
There are typically three words in geometry that are undefined. The first is "point." A point has no dimension, length, width, or thickness. The second is "line." A line has no thickness and goes on indefinitely in both directions. The third undefined term is "plane." A plane has no thickness and has no boundaries.
The term 'undefined' means not precisely limited, determined, or distinguished not precisely limited, determined, or distinguished; "an undefined term"; "undefined authority"; "some undefinenot precisely limited, determined, or distinguished; "an undefined term"; "undefined authority"; "some undefine
