 This article will help you solve direction sense problems in the reasoning section of various competitive exams.  Essentially, Direction sense problems are based on two principles- Distance Direction    POINTS TO REMEMBER Each main direction change undergoes a 90° change in direction e.g. from North to West/East it will be 90° change.  Whenever a person moves to his left side, he will move towards anti- clockwise direction. Whenever a person moves to his right side, he will move towards clockwise direction. Change between North and North-east is only 45°.  We assume all these distances to be along straight lines and between specified points.  A person facing north, on taking left will face towards west and on taking the right turn towards east. A person facing west, on taking left will face towards south and on taking right turn towards north. A person facing east, on taking left will face towards north and on taking the right turn towards south. A person facing south, on taking left will face towards east and on taking the right turn towards west.
 PYTHAGORAS THEOREM We'll use the concept of Pythagoras theorem to solve the questions on directions. In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
