Question

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

figure	type	how to write it
(b) <--m----l (l is a dot)	⚪line ⚪ray ⚪line segment	blank
(c) g•----h•	⚪line ⚪ray ⚪line segment	blank

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 can be written using two points on it with a double - headed arrow. So it's written as $\overleftrightarrow{JK}$.

Step1: Identify the type

A ray has a starting point and extends infinitely in one direction. The figure has a starting point (L) and an arrow on the other end (through M), so it's a ray.

Step2: Write the notation

A ray is written with the starting point first, followed by another point on the ray, with a single - headed arrow. So it's written as $\overrightarrow{LM}$.

Step1: Identify the type

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

Step2: Write the notation

A line segment is written using its two endpoints with a bar over them. So it's written as $\overline{GH}$.

Answer:

Type: line; How to write it: $\overleftrightarrow{JK}$
