Question

which defines a line segment in the ray below? a b c
(overline{bc})
(overleftrightarrow{ac})
(overline{abc})
(overrightarrow{ac})

Explanation:

Step1: Recall line - segment notation

A line - segment is a part of a line that is bounded by two distinct end - points. It is denoted by a bar over the two endpoints.

Step2: Analyze the options

• $\overline{BC}$ represents the line - segment with endpoints $B$ and $C$.
• $\overleftrightarrow{AC}$ represents the line passing through $A$ and $C$.
• $\overline{ABC}$ is an incorrect notation as a line - segment has two endpoints.
• $\overrightarrow{AC}$ represents the ray starting at $A$ and passing through $C$.

Answer:

A. $\overline{BC}$
