Directions

Video Lesson on Directions

Direction and Distance-based questions are asked in various exams. Every employment exam including GAT and IBP and admission test like NUST NET will have more than one question related to this topic. Direction and Distance type questions check one’s sense of directions and ability to visualize.

These questions are generally very easy but occasionally you get tricky ones. Expect questions from many left and right turns. You may have questions with distances measured differently in meters, km etc. You may also be tested on your ability to resolve relative directions like North – East, South – West etc.

Direction is a path along which someone or something moves.

In the topic, all the questions are based on four main directions (i.e. East, West, North, and South) and four cardinal directions (i.e. North-East, North-West, South-East, and South-West). Based on given scenario we have to find out either direction or distance from given place.

Importance of topic

Direction and Distance type questions check one’s sense of directions and ability to visualize.

Pre-Requisites

Direction sense - There are four main directions East, West, North and South. We will denote it as E, W, N and S respectively.

There are four Cardinal Directions that exist between four main directions namely North-East, North-West, South-East, and South-West. We will represent them as NE, NW, SE, and SW.

Angle

Now one thing we have to remember is that angle between two main directions is always 90° and the angle between main direction and its adjacent cardinal direction is always 45°.

Selection of right or left direction depends on whether it is clockwise (Right turn) or anti-clockwise (Left turn).

Example

A boy is facing towards the west and turns 45° clockwise.

So, in this case, Boy will turn on his right side 45°.

If it was 45° ANTI-CLOCKWISE then Boy will turn on his left 45°.

Pythagoras Theorem

In Pythagoras Theorem, relation between three sides of the right angle triangle is defined. This theorem is helpful in measuring distance between given points.

(Hypotenuse)2 = (Perpendicular)2 + (Base)2

(AC)2 = (AB)2 + (BC)2

Always consider yourself as facing North. Solve the question accordingly. Now your left hand is to the West side and your right hand is to the East side.

Key Points

  • There would be no Shadow at 12Noon.
  • After sun rise till 12PM, shadow would be towards west.
  • After 12PM and before sun set, shadow would be towards east.
  • If a person faces towards North before 12pm, his/her shadow would be towards his/her left side and after 12pm it would be towards his/her right side.
  • If a person faces towards South before 12pm, his/her shadow would be towards his/her right side and after 12pm it would be towards his/her left side.
  • Right, and Left turn always make 90° angle.
