Video on Directions
Direction - "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.
This type of questions are asked in IBPS PO, IBPS Clerk, CMAT, GMAT, CAT, SSC CGL, Clerical, CET, etc.
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 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 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
Key Points
1) There would be no Shadow at 12Noon.
2) After sun rise till 12PM, shadow would be towards west.
3) After 12PM and before sun set, shadow would be towards east.
4) 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.
5) 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.
6) Right and Left turn always make 90° angle.
Question Types
1) Direction based Questions
In these types of questions, student is asked to find out direction from one point to another. This point can be starting position, current position or any other place.
Examples
A) Joe is walking towards North for 15 miles, turns left and walks another 10 miles. He then turns right and walks 10 miles. Now, he again turns right and walks 30 miles. Which direction is he from Starting point?
a) South-East
b) North-East
c) North-West
d) South-West
e) None of these
Answer: b) North-East
Diagram:
B) Morris is facing North and walks 10kms. He turns 270° anti-clockwise and walks 15kms. Now, he again turns 45° clockwise and walks for 25kms. Which direction is he facing now?
a) North-West
b) South-West
c) North-East
d) South-East
e) None of these
Answer: d) South-East
Diagram:
C) Joe is facing towards South and turns 45° anti-clockwise. He turns again 180° in anti-clockwise direction. Now, he turns 270° clockwise. Which direction is he facing?
a) West
b) East
c) South-West
d) North-East
Answer: c) South-West
Diagram:
D) Mary is walking towards South-West for 15 miles, turns right and walks another 10 miles. She then turns 90° Clockwise and walks 10 miles. Now, she again turns left and walks 30 miles. Which direction is she facing?
a) East
b) West
c) South-East
d) North-West

2) Distance based Questions
In these types of questions, student is asked to find out distance from one point to another. This point can be starting position, current position or any other place.
This question will require Pythagoras theorem in some cases, while in some cases we can easily find out distance between two points by simply drawing diagrams.
Examples
A) Joe went 35 meters towards east from Mary’s house. He turns left and walks 15 meters. Now, he takes a left turn and walks 80 meters. Finally, he turns left and walks for 15 meters. How far Joe is from Mary’s house?
a) 30
b) 45
c) 50
d) 65
Answer: b) 45
Diagram:
B) Maria walked 30 m towards north. She turned right and walked 40 m. She then turned right and walked 45 m. She turned left and walked 25 m. Finally she turned left and walked 15 m. How far is she from the starting position?
a) 55
b) 65
c) 30
d) 45
Answer: b) 65
Diagram:
C) Harry walks 25 meters towards North from his friend’s house. Then he turns left and walks 32 meters. He again turns left and walks 25 meters. Further, he moves 25 meters after turning to his right. How far is he from his friend’s house?
a) 50
b) 7
c) 57
d) 0
e) Can’t determined
Answer: c) 57
Diagram:
D) A Boy walks 12kms towards east. He turns 90° clockwise and walks 20kms then he turned right and walked for 33kms. How far is he from starting point?
a) 65
b) 29
c) 21
d) 43
Answer: b) 29

3) Direction-Distance based Questions
In this type of questions, we deal with the final distance and directions between two points; it can be places, persons, things, etc.
