\n" ); document.write( "\n" ); document.write( "in triangle one side is always $\"less\"$ then the $\"sum\"$ of two other sides,
\n" ); document.write( "so, if\r

\n" ); document.write( " $\"DE=30\"$
\n" ); document.write( "and $\"CE=45\"$
\n" ); document.write( " we can say that
\n" ); document.write( " $\"CD\"$ < $\"DE\"$ + $\"CE\"$
