Question

which defines a line segment in the ray below? options: \\(\overline{bc}\\), \\(\overrightarrow{ac}\\), \\(\overleftrightarrow{ac}\\), \\(\overline{abc}\\)

Explanation:

A line segment is defined by two endpoints with a bar over them, no arrow. $\overrightarrow{AC}$ and $\overleftarrow{AC}$ are rays (have arrows indicating direction), and $\overline{ABC}$ is not a valid segment notation (segments use 2 endpoints). $\overline{BC}$ has two endpoints B and C with a bar, fitting the line segment definition.

Answer:

$\boldsymbol{\overline{BC}}$
