Question

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

figure	type	how to write it
(b) • q ———• p	∘ line ∘ ray ∘ line segment
(c) • s ———• r →	∘ line ∘ ray ∘ line segment

(also, some buttons on the right: icons and 5, x.)

Explanation:

Part (a)

Step1: Identify the type

A line extends infinitely in both directions. The figure has arrows on both ends, so it's a line.

Step2: Write the notation

A line through points \( T \) and \( U \) is written as \( \overleftrightarrow{TU} \).

Step1: Identify the type

A line segment has two endpoints. The figure has two endpoints \( Q \) and \( P \), so it's a line segment.

Step2: Write the notation

A line segment with endpoints \( Q \) and \( P \) is written as \( \overline{QP} \) (or \( \overline{PQ} \)).

Step1: Identify the type

A ray has one endpoint and extends infinitely in one direction. The figure has an endpoint \( S \) and an arrow towards \( R \), so it's a ray.

Step2: Write the notation

A ray with endpoint \( S \) passing through \( R \) is written as \( \overrightarrow{SR} \).

Answer:

Type: line; How to write it: \( \overleftrightarrow{TU} \)
