Question

classify each figure as a line, ray, or line segment. then, show how to write it
figure\ttype\thow to write it
(a) figure with points c, d, arrows both ends\t○ line ○ ray ○ line segment\tblank
(b) figure with points e, f, arrow left, f is endpoint\t○ line ○ ray ○ line segment\tblank
(c) figure with points h, a, both endpoints\t○ line ○ ray ○ line segment\tblank

Explanation:

Part (a)

Step1: Identify the figure 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 \( C \) and \( D \) is written as \( \overleftrightarrow{CD} \).

Step1: Identify the figure type

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

Step2: Write the notation

A ray with endpoint \( F \) passing through \( E \) is written as \( \overrightarrow{FE} \).

Step1: Identify the figure type

A line segment has two endpoints and a definite length. The figure has endpoints at \( H \) and \( A \), so it's a line segment.

Step2: Write the notation

A line segment between \( H \) and \( A \) is written as \( \overline{HA} \).

Answer:

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