Question

identify all rays and lines in the picture below
rays: $overrightarrow{bd}$, $overrightarrow{ab}$
lines: $overleftrightarrow{ac}$, $overrightarrow{bd}$, $overrightarrow{ab}$
rays: $overrightarrow{bd}$, $overrightarrow{ab}$
lines: $overleftrightarrow{ac}$
rays: $overrightarrow{bd}$, $overrightarrow{ac}$, $overrightarrow{ab}$
lines: $overleftrightarrow{ac}$
rays: $overrightarrow{bd}$, $overrightarrow{ca}$, $overrightarrow{ac}$, $overrightarrow{ab}$

Explanation:

A ray has one endpoint and extends infinitely in one direction; a line extends infinitely in both directions.

1. Rays: $\overrightarrow{BD}$ (endpoint B, extends through D), $\overrightarrow{AB}$ (endpoint A, extends through B), $\overrightarrow{CA}$ (endpoint C, extends through A), $\overrightarrow{AC}$ (endpoint A, extends through C) match the ray definitions from the diagram.
2. Line: $\overleftrightarrow{AC}$ is the only line, as it extends infinitely in both directions through A and C.

Answer:

Rays: $\overrightarrow{BD},\overrightarrow{CA},\overrightarrow{AC},\overrightarrow{AB}$
Lines: $\overleftrightarrow{AC}$
(The fourth option is the correct choice)
