means &quot;the measure of line segment AB is equal to the measure of line segment CD&quot;


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \overline{AB}]&lt;font face=&quot;Math1&quot;&gt; @ &lt;/font&gt;&lt;font face=&quot;Times New Roman&quot;&gt; *[tex \LARGE \overline{CD}]

For most purposes, they are virtually identical statements.  However, remember Mark Twain&#39;s admonition: &quot;The difference between the right word and almost the right word is the difference between lightning and the lightning bug.&quot;
