Question

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

Explanation:

Step1: Recall ray - line relationship

A line is composed of two opposite - directed rays with the same initial point. For line BE, the rays that make it up are those with an initial point on the line and extend in the directions of the line.

Step2: Identify correct rays

Ray $\overrightarrow{AB}$ and ray $\overrightarrow{AE}$ have the initial point A which lies on the line BE and extend in the directions along the line BE.

Answer:

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