Question

which rays are part of line be?
○ $overrightarrow{ac}$ and $overrightarrow{ae}$
○ $overrightarrow{ab}$ and $overrightarrow{ae}$
○ $overrightarrow{ac}$ and $overrightarrow{ab}$
○ $overrightarrow{ab}$ and $overrightarrow{af}$

Explanation:

Step1: Recall ray - line relationship

A line can be thought of as composed of two opposite - directed rays with a common endpoint. For line BE, the rays that make it up are the ones starting from a point on the line and extending infinitely in one of the two directions along the line.

Step2: Identify relevant rays

The rays $\overrightarrow{AB}$ and $\overrightarrow{AE}$ together form the line BE. $\overrightarrow{AB}$ extends infinitely in the direction from A towards B and $\overrightarrow{AE}$ extends infinitely in the direction from A towards E.

Answer:

$\overrightarrow{AB}$ and $\overrightarrow{AE}$
