<p>In geometry a line:</p>
|
|
<ul>
|
|
<li>is straight (no bends),</li>
|
|
<li>has no thickness, and</li>
|
|
<li>extends in both directions without end (infinitely).</li>

<h2>Play With It</h2>
|
|
|

<p>Change the position of points <b>A</b> and <b>B</b>. Note that the line <b>AB</b> extends forever in both directions:</p>
