fill in the blanks to make the statements true.
Two lines in a plane which never meet at any point are called _________.

Answer

To solve the question, we need to fill in the blank in the statement: "Two lines in a plane which never meet at any point are called _________."

### Step-by-Step Solution:

1. **Understanding the Concept**: We start by understanding what it means for two lines to never meet. In geometry, when two lines do not intersect at any point, they maintain a constant distance from each other.

2. **Identifying the Type of Lines**: The lines that never meet are characterized by their behavior in a plane. They can be extended infinitely in both directions without intersecting.

3. **Defining the Lines**: The specific term used to describe two lines that do not meet at any point is crucial.

4. **Filling in the Blank**: Based on the definition, we can conclude that the correct term to fill in the blank is "parallel lines."

5. **Final Statement**: Therefore, the completed statement is: "Two lines in a plane which never meet at any point are called parallel lines."

### Final Answer:
Two lines in a plane which never meet at any point are called **parallel lines**.
