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 ray has one endpoint and extends infinitely in one - direction. A line segment has two endpoints. A line extends infinitely in both directions.

Step2: Analyze figure (a)

It has one endpoint (C) and extends infinitely in the direction of D, so it is a ray. It is written as $\overrightarrow{CD}$.

Step3: Analyze figure (b)

It has two endpoints (E and F), so it is a line segment. It is written as $\overline{EF}$.

Step4: Analyze figure (c)

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

Answer:

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