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 can be thought of as composed of two opposite - directed rays. A ray has one endpoint and extends infinitely in one direction. For line BE, the rays that make it up are those with endpoints on the line and extending in the directions along the line.

Step2: Identify relevant rays

The rays $\overrightarrow{AB}$ and $\overrightarrow{AE}$ have the common point A which lies on line BE and they extend in the directions along line BE.

Answer:

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