Question

what are all the ways to properly name this line? a b c m abc or cba (overline{ab},overline{bc},overline{ac}) line m, (overline{ab},overline{bc},overline{ac}) (overleftrightarrow{ab},overleftrightarrow{bc},overleftrightarrow{ac})

Explanation:

A line can be named by using a single lowercase letter (like line $m$) or by using two or more points on the line with a double - headed arrow above them. $\overleftrightarrow{AB}$, $\overleftrightarrow{BC}$, $\overleftrightarrow{AC}$ are all valid ways to name the line using points, and $m$ is also a valid name for the line.

Answer:

Line $m$, $\overleftrightarrow{AB}$, $\overleftrightarrow{BC}$, $\overleftrightarrow{AC}$
