Question

1. classify each figure as a line, ray, or line segment. then, show how to write it.

(a) figure
type: line segment
how to write it:
(b) figure
type:
how to write it:
(c) figure
type:
how to write it:

Explanation:

Step1: Recall definitions

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

Step2: Analyze figure (a)

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

Step3: Analyze figure (b)

It has two endpoints A and B, so it is a line segment. It can be written as $\overline{AB}$.

Step4: Analyze figure (c)

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

Answer:

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