Question

multiple choice 1 point
which of the following is the appropriate way to name the line connecting points a and d.
options:
\\( \overrightarrow{ad} \\)
\\( \overline{ad} \\)
\\( \angle ad \\)
\\( \overleftrightarrow{ad} \\)

Explanation:

A line (not a ray or segment) connecting two points is named with a bar over the two points without an arrow, as it extends infinitely in both directions. $\overrightarrow{AD}$ and $\overleftarrow{AD}$ represent rays (one direction), and $\angle AD$ represents an angle, which is incorrect.

Answer:

$\overline{AD}$
