Answer 1

In geometry, the undefined notions are basic concepts that cannot be formally defined but are understood intuitively. These typically include terms like "point," "line," and "plane."

From the options you've provided, "A line is an example of an undefined notion" is correct. Therefore, the answer is:

**A line is an example of an undefined notion.**
