Question

classify each figure as a line, ray, or line segment. then, show how to write it.
(a)
(b)
(c)

Explanation:

Step1: Recall definitions

A line extends infinitely in both directions, a ray extends infinitely in one - direction starting from a point, and a line segment has two endpoints.

Step2: Analyze figure (a)

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

Step3: Analyze figure (b)

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

Step4: Analyze figure (c)

It has two endpoints (C and D), so it is a line segment. It is written as $\overline{CD}$.

Answer:

(a) Type: ray, How to write it: $\overrightarrow{EF}$
(b) Type: line, How to write it: $\overleftrightarrow{AB}$
(c) Type: line segment, How to write it: $\overline{CD}$
