From South to West to Northeast and Back Again
Video on Directions
Direction - "A path along which someone or something moves."
In the topic, all the questions are based on four primary directions (i.e. East, West, North and Southward) and four fundamental directions (i.e. North-East, North-W, South-E and S-West).
Based on given scenario we have to detect out either direction or distance from given place.
Importance of topic
Direction and Distance type questions bank check 1's sense of directions and ability to visualize.
This type of questions are asked in IBPS PO, IBPS Clerk, CMAT, GMAT, True cat, SSC CGL, Clerical, CET, etc.
Pre-Requisites
Direction sense - There are four main directions Due east, West, Due north and Southward. We will denote information technology every bit E, Westward, Northward and S respectively.
At that place are four Cardinal Directions that exist between four main directions namely Northward-East, N-West, S-Due east and South-Westward. We volition correspond them as NE, NW, SE and SW.
Angle - Now 1 thing we have to remember is that angle betwixt two chief directions is ever 90° and angle between principal management and its adjacent cardinal direction is always 45°.
Choice of right or left direction depends on whether it is clockwise (Right turn) or anti-clockwise (Left turn).
Example: A male child is facing towards west and turns 45° clockwise.
So in this case Boy will turn on his correct side 45°.
If information technology was 45° ANTI-CLOCKWISE then Boy volition plough on his left 45°.
Pythagoras Theorem
In Pythagoras Theorem, relation between three sides of the right bending triangle is defined.
This theorem is helpful in measuring distance between given points.
(Hypotenuse)2 = (Perpendicular)ii + (Base of operations)two
(AC)2 = (AB)ii + (BC)2
Key Points
1) There would be no Shadow at 12Noon.
ii) Later on sun rise till 12PM, shadow would be towards west.
3) Later on 12PM and earlier dominicus set, shadow would be towards e.
iv) If a person faces towards N before 12pm, his/her shadow would exist towards his/her left side and afterward 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.
six) Correct and Left plow e'er make xc° bending.
Question Types
i) Direction based Questions
In these types of questions, student is asked to find out direction from one point to some other. This point can exist starting position, current position or whatever other place.
Examples

a) South-East
b) North-E
c) North-West
d) South-Due west
eastward) None of these
Answer: b) N-East
Diagram:

ii) Distance based Questions
In these types of questions, student is asked to detect out distance from one betoken to another. This point can be starting position, current position or whatsoever other place.
This question will require Pythagoras theorem in some cases, while in some cases we tin easily discover out distance between two points by simply cartoon diagrams.
