identify all rays and lines in the picture below.
rays: \\(\overrightarrow{xw},\overrightarrow{zy}\\)
lines: \\(\overleftrightarrow{xz}\\)
rays: \\(\overrightarrow{xw},\overrightarrow{zy}\\)
lines: \\(\overleftrightarrow{xz},\overleftrightarrow{xw},\overleftrightarrow{zy}\\)
rays: \\(\overrightarrow{xw},\overrightarrow{xz},\overrightarrow{zy}\\)
lines: \\(\overleftrightarrow{xz}\\)
rays: \\(\overrightarrow{xw},\overrightarrow{xz},\overrightarrow{zx},\overrightarrow{zy}\\)
lines: \\(\overleftrightarrow{xz}\\)

Explanation:

Step1: Recall definitions

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

Step2: Identify rays

From the figure, with a single - endpoint and infinite extension in one direction, the rays are $\overrightarrow{XW}$ and $\overrightarrow{ZY}$.

Step3: Identify lines

The line that extends infinitely in both directions is $\overleftrightarrow{XZ}$.

Answer:

Rays: $\overrightarrow{XW}$, $\overrightarrow{ZY}$; Lines: $\overleftrightarrow{XZ}$
