document.write( "Notice that the side AB is vertical of the length 5 - (-1) = 6 units\r\n" );
document.write( "\r\n" );
document.write( "       and  the side AC is horizontal with the length 3 - (-5) = 8 units.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the triangle ABC is a right angled triangle with the right angle A and the legs of 6 and 8 units.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is a classic (3,4,5) right angled triangle with the hypotenuse BC of 10 units long.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hypotenuse is the longest side.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The length of the longest side is 10 units.\r\n" );
