Question

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

Explanation:

Step1: Identify the type of figure (a)

A line extends infinitely in both directions. Figure (a) has arrows at both ends, so it is a line.

Step2: Write figure (a)

It is written as $\overleftrightarrow{DC}$.

Step3: Identify the type of figure (b)

A line - segment has two endpoints. Figure (b) has two endpoints $F$ and $E$, so it is a line - segment.

Step4: Write figure (b)

It is written as $\overline{FE}$.

Step5: Identify the type of figure (c)

A ray has one endpoint and extends infinitely in one direction. Figure (c) has one endpoint $A$ and an arrow in one direction, so it is a ray.

Step6: Write figure (c)

It is written as $\overrightarrow{AB}$.

Answer:

(a) Type: line; How to write it: $\overleftrightarrow{DC}$
(b) Type: line segment; How to write it: $\overline{FE}$
(c) Type: ray; How to write it: $\overrightarrow{AB}$
