Question

A line blank has endpoints

Answer 1

Answer: A line never has endpoints .

Step-by-step explanation:

In geometry , a line is a straight one-dimensional undefined figure which  extends infinitely in both directions.

Thus , a line contains no endpoints because it is extending infinitely in both the directions.

If a line has one end point then we call it a ray and if it has both endpoints then we call it line-segment.

Therefore , the complete sentence will be : A line never has endpoints

Answer 2

While a line *segment* (note the emphasis on "segment") has two endpoints, a line itself does not have any endpoints. 

A geometric line extends forever in both directions infinitely. So the answer here is "never"

In other words, the full phrase would be "a line never has endpoints".
