document.write( "0 sides and 0 diagonals.  In other words, the polygon is degenerated into a\r\n" );
document.write( "single point, which has no sides and no diagonals.  In higher geometry courses\r\n" );
document.write( "that is allowed.  But in lower level geometry it is not.  If you are in a\r\n" );
document.write( "lower level of geometry, then the answer is \"There are no such polygons,\r\n" );
document.write( "because there must always be 2 fewer diagonals than sides\".\r\n" );
