YOUR QUESTION IS AMBIGUOUS.
\n" ); document.write( "IF ABC ARE COLLINEAR..THEY ARE ALL ON SAME LINE.SO THEY ARE ALL ONE RAY.
\n" ); document.write( "IF WE DISTINGUISH IN DIRECTION THEN AC AND CA ARE DIFFERENT.
\n" ); document.write( "IF WE DISTINGUISH BETWEEN START AND END POINTS ALSO THEN WE SHALL HAVE
\n" ); document.write( "AB......BA
\n" ); document.write( "AC......CA
\n" ); document.write( "BC......CB
\n" ); document.write( "THAT IS 6 IN ALL NOT 4 AS YOU HAVE MENTIONED...
\n" ); document.write( "SO WHAT EXACTLY YOU WANT?
\n" ); document.write( "ON THAT BASIS THE ANSWER WILL DEPEND.
