Lesson 1: Types of plane figures

# Lines, line segments, and rays review

Review the basics of lines, line segments, and rays.  Identify and draw lines, line segments, and rays in practice problems.

## What are $\text{lines}$‍  and $\text{line segments}$‍  and $\text{rays}$‍ ?

A $\text{line}$ extends forever in both directions, like this:
A $\text{line segment}$ is just part of a line. It has two endpoints, like this:
A $\text{ray}$ starts at one point and continues on forever in one direction, like this:

## Practice set 1: Identify lines, line segments, and rays

Problem 1A
Which of the following figures show a dashed $\text{ray}$?
Consider the entire dashed structure in each figure.

## Practice set 2: Draw lines, line segments, and rays

Problem 2A
Drag the lines so one line goes through points $\text{A}$ and $\text{D}$, and the other line goes through points $\text{B}$ and $\text{C}$.
These are lines because they each have
and continue forever in
.

• this stuff is very easy i think
a ray is a line that has one endpoint and on one side it goes on forever
a line goes on forever in both directions
a line segment has two endpoints
• I agree I love math
• Why is it two endpoints?
• Because two endpoints for a line segment means it cannot continue in either direction. Hope this helps!
• How do the lines get there names?
• it is in lesson 2
• How do i do the work sheet with the lines you have to drag? Its not working for me.
• you can draw the line segments in pencil.
• A ray is a line that never stops from one side

• it keeps saying I'm not doing it when I'm doing it is some type of glitch
• If you hit the refresh button it should work
• I put it right next to D but I got it wrong so I had to put it on D.What a waste of time.
• 30 minute timer is almost done!
