Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on you. identify all rays and lines in the picture below. rays: $overrightarrow{ea}$, $overrightarrow{eb}$, $overrightarrow{ec}$, $overrightarrow{ed}$, $overrightarrow{de}$, $overrightarrow{be}$ lines: $overleftrightarrow{ed}$, $overleftrightarrow{be}$ rays: $overrightarrow{ea}$, $overrightarrow{eb}$, $overrightarrow{ec}$, $overrightarrow{ed}$ lines: $overleftrightarrow{ed}$, $overleftrightarrow{be}$ rays: $overrightarrow{ea}$, $overrightarrow{ec}$ lines: $overleftrightarrow{ed}$, $overleftrightarrow{be}$ rays: $overrightarrow{ea}$, $overrightarrow{ec}$ lines: $overleftrightarrow{ed}$, $overleftrightarrow{be}$, $overleftrightarrow{ea}$, $overleftrightarrow{ec}$

Explanation:

A ray has one - endpoint and extends infinitely in one direction. A line extends infinitely in both directions. From point E, rays are $\overrightarrow{EA}$, $\overrightarrow{EB}$, $\overrightarrow{EC}$, $\overrightarrow{ED}$. Lines are $\overleftrightarrow{ED}$ and $\overleftrightarrow{BE}$.

Answer:

B. Rays: $\overrightarrow{EA}$, $\overrightarrow{EB}$, $\overrightarrow{EC}$, $\overrightarrow{ED}$; Lines: $\overleftrightarrow{ED}$, $\overleftrightarrow{BE}$
