Question

classify each figure as a line, ray, or line segment. then, show how to write it.
(a)
figure: t u (a line - like figure with two endpoints)
type:
○ line
○ ray
○ line segment
how to write it:
(b)
figure: q p (a figure with an arrow - like end)
type:
○ line
○ ray
○ line segment
how to write it:
(c)
figure: s r (a figure with arrows on both ends)
type:
○ line
○ ray
○ line segment
how to write it:

Explanation:

Step1: Identify figure (a)

It has two endpoints T and U, so it's a line - segment.

Step2: Write figure (a)

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

Step3: Identify figure (b)

It has one endpoint P and extends infinitely in one direction through Q, so it's a ray.

Step4: Write figure (b)

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

Step5: Identify figure (c)

It extends infinitely in both directions through S and R, so it's a line.

Step6: Write figure (c)

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

Answer:

(a) Type: line segment; How to write it: $\overline{TU}$
(b) Type: ray; How to write it: $\overrightarrow{PQ}$
(c) Type: line; How to write it: $\overleftrightarrow{SR}$
