Question

classify each figure as a line, ray, or line segment. then, show how to write it.
(a) figure: figure with points k and j and arrowheads on both ends type: o line o ray o line segment how to write it: empty box
(b) figure: figure with points g and h and no arrowheads type: o line o ray o line segment how to write it: empty box
(c) figure: figure with points m and l and an arrowhead on one end type: o line o ray o line segment how to write it: empty box

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)

The figure with two arrow - heads extending infinitely in both directions is a line. It is written as $\overleftrightarrow{KJ}$.

Step3: Analyze figure (b)

The figure with two endpoints $G$ and $H$ is a line segment. It is written as $\overline{GH}$.

Step4: Analyze figure (c)

The figure with one endpoint $M$ and extending infinitely in the direction of $L$ is a ray. It is written as $\overrightarrow{ML}$.

Answer:

(a) Type: line; How to write it: $\overleftrightarrow{KJ}$
(b) Type: line segment; How to write it: $\overline{GH}$
(c) Type: ray; How to write it: $\overrightarrow{ML}$
