Name this line. Check all that apply.

•  $\overrightarrow{AB}$  

•  $\overleftarrow{A}\overrightarrow{B}$  

•  $\overleftarrow{C}\overrightarrow{B}$  

•  $\overline{AB}$  

•  $\overleftarrow{AB}\overrightarrow{C}$  

Name two line segments.

• $\overline{AB}$

• $\overleftarrow{C}\overrightarrow{B}$

• $\overline{BC}$

• $\overleftarrow{B}\overrightarrow{C}$

• $\overline{ABC}$
