\n" );

The easiest point to rotate through 90 degrees counterclockwise is the point that is on one of the axes, namely (0,2).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If you rotate (0,2) 90 degrees to the left, then you end up at (-2,0). \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Next the original point (-2,4) is 2 units up and 2 units left of (0,2), so the rotation of (-2,4) is goint to be 2 units down and 2 units right of (-2,0) (which is the rotation of (0,2). That is: (-4,-2).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Next, the original point (-4,2) is on the horizontal line through the original point (0,2) and 4 units to the left. So the rotation of (-4,2) has to be on a vertical line with (-2,0), the rotation of (0,2), and 4 units down.
