Question

which of the following is a ray drawn in the figure below?

Explanation:

Step1: Recall ray definition

A ray has one endpoint and extends infinitely in one direction.

Step2: Analyze each option

• $\overrightarrow{UX}$: Has two distinct endpoints $U$ and $X$, so it's a line - segment.
• $\overrightarrow{TW}$: Has two distinct endpoints $T$ and $W$, so it's a line - segment.
• $\overrightarrow{YU}$: Has endpoint $Y$ and extends infinitely through $U$, so it is a ray.
• $\overrightarrow{WX}$: Has two distinct endpoints $W$ and $X$, so it's a line - segment.

Answer:

$\overrightarrow{YU}$
