The easiest way to see this is to merely graph it.
\n" ); document.write( "Since you are rotating it counterclockwise 90 degrees, merely tilt your head
\n" ); document.write( "90 degrees CLOCKWISE and then tell me the coordinates of C as it appears to you now...yes, that's it...(2, 3)!
\n" ); document.write( "
\n" );
