The \"Triangle Proportionality Theroem\" states: If a line is parallel to one side of a triangle and intersects the other two sides in two distinct points, then it separates these sides into segments of proportional length.\r

\n" ); document.write( "\n" ); document.write( "AD = 2\r
\n" ); document.write( "\n" ); document.write( "DB = 3\r
\n" ); document.write( "\n" ); document.write( "AE = 4\r
\n" ); document.write( "\n" ); document.write( "EC = 4\r
\n" ); document.write( "\n" ); document.write( "We now have two fractions:\r
\n" ); document.write( "\n" ); document.write( "2/3 and 4/4\r
\n" ); document.write( "\n" ); document.write( "QUESTION:\r
\n" ); document.write( "\n" ); document.write( "Are these two fractions the same?\r
\n" ); document.write( "\n" ); document.write( "No, right?\r
\n" ); document.write( "\n" ); document.write( "So, the answer to your question is NO: DE is NOT parallel to BC\r
