A circle is an undefined notion. A circle is an undefined notion. An angle is an example of an undefined notion. An angle is an example of an undefined notion. A line segment is an example of an undefined notion.

Answer 1

In geometry, the undefined notions are typically basic concepts that form the foundation for further definitions and theorems. Among the options provided, the following is the correct answer:

A line is an example of an undefined notion.

Lines, points, and planes are commonly accepted as undefined notions in geometry, while circles, angles, and line segments are generally defined in terms of these undefined notions.
