Question

Which of the following is true about line segments?

• A. It has endpoints.
• B. Can be extended infinetly.
• C. It can be measured.
• D. It has fixed length.

Answer 1

Answer: (A), (C), (D)

The correct options are
A It has endpoints.
C It can be measured.
D It has fixed length.


Here, P and Q are the two end points. So, the distance between $P$ and $Q$ can be measured. Hence, the length of $\overline{PQ}$ is fixed.
The length of a line segment can be measured. Since it has two endpoints, the length is fixed.
