The north direction on the map is shown with the help of an compass

Answer 2

Answer:

Most maps in modern times indicate direction by using north along with an upward pointing arrow on the two-dimensional plane. This is supported and influenced by the discovery of modern compass (Europe 1200 - 1500) that points to the magnetic north and also because of the widespread belief that the earth rotates on its axis in the direction of the "North Star". This notion of the north being upward at the right was established by Ptolemy in 90-168 AD who was a Greek astronomer, as the majority of the better place were in the northern hemisphere and were easy to study in place at the "upper right-hand corner".
