Question

classify each figure as a line, ray, or line segment. then, show how to write it.
(a) figure: a figure with points a and b, with an arrow pointing left starting from a
type: ○line ○ray ○line segment
how to write it:
(b) figure: a figure with points e and f, with arrows pointing left and right
type: ○line ○ray ○line segment
how to write it:
(c) figure: a figure with points c and d, with no arrows
type: ○line ○ray ○line segment
how to write it:

Explanation:

Step1: Classify Figure (a)

It has one endpoint (B) and extends infinitely in one direction, so it is a ray. Written as $\overrightarrow{BA}$

Step2: Classify Figure (b)

It extends infinitely in both directions, so it is a line. Written as $\overleftrightarrow{EF}$

Step3: Classify Figure (c)

It has two endpoints (C and D) with no infinite extension, so it is a line segment. Written as $\overline{CD}$

Answer:

Figure	Type	How to write it
(b)	line	$\overleftrightarrow{EF}$
(c)	line segment	$\overline{CD}$
