\n" ); document.write( "\n" ); document.write( "Theorem: The sum of the lengths of any two sides of a triangle must be greater than the third side.\r
\n" ); document.write( "\n" ); document.write( "\"x%2B+2x%2B1%3E10\"\r
\n" ); document.write( "\n" ); document.write( "\"3x%3E10-1\"\r
\n" ); document.write( "\n" ); document.write( "\"3x%3E9\"\r
\n" ); document.write( "\n" ); document.write( "\"x%3E3\"\r
\n" ); document.write( "\n" ); document.write( "or
