We often call "undefined terms" variables. Their value is not known; it can vary. And thus the name we assign them is variable.
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.
I am prepared to define any term in geometry. If there is some term for which you would like to have a definition, just ask.
there isn't a need
The three undefined terms are the point,the line and the plane.
The answer depends on which undefined terms the question refers to.

It is a very basic concept which cannot be defined. Undefined terms are used to define other concepts. In Euclidean geometry, for example, point, line and plane are not defined.

"Defined items" are defined in terms of "undefined terms".

The pair of undefined terms used to define parallel lines is "line" and "point." Parallel lines are defined as two lines in a plane that do not intersect, regardless of how far they are extended, and a point is used to describe the position relative to these lines. These terms are foundational in geometry, serving as the basis for more complex definitions and theorems.
