\n" ); document.write( "\n" ); document.write( "since distance between $\"L\"$ ( $\"0\"$ , $\"4\"$ ) and $\"N\"$ ( $\"2\"$ , $\"4\"$ ) is $\"2\"$ units, and $\"LN=OM\"$ , the distance between fourth vertice $\"O\"$ and $\"M\"$ ( $\"6\"$ , $\"+0\"$ ) will be also $\"2\"$ units to the left\r
\n" ); document.write( "\n" ); document.write( "if $\"M\"$ ( $\"6\"$ , $\"+0\"$ ) $\"2\"$ units to the left will be at point ( $\"4\"$ , $\"0\"$ )\r
