Lesson 1: Lines, line segments, and rays

# 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
