A plane is a flat surface with edges.

A point looks like a period.
A point looks like a period.

A line extends forever in one direction.
A line extends forever in one direction.

Spaces are two-dimensional shapes.

Answer 1

An undefined term in geometry is a basic concept that does not have a formal definition but can be described and understood through examples and properties. Among the options provided, the statement that best fits this description is:

"A point looks like a period."

This suggests that a point is a basic concept (or undefined term) in geometry that does not have a specific definition but can be approximated visually. Points, lines, and planes are all considered undefined terms in geometry, whereas the other options contain inaccuracies (e.g., a plane does not have edges, and a line extends infinitely in both directions, not just one).

The best answer to identify an undefined term in this context is:

**A point looks like a period.**
