Direction is a measurement of position of one thing with respect to another thing or a reference point. Distance between two points is a measurement of the shortest distance, i.e., the displacement between the two points.

The shortest distance between two points may be different from the total distance covered in going from one point to the other.

The problems based on direction and distance have instructions regarding the movement of a person or an object from a starting point (also called origin) upto an end point (also called destination).

These instructions generally provide magnitude as well as direction of the movement. These questions are designed to test the candidate’s ability to sense direction.

Direction can be classified as main directions and sub-directions.

**Main Directions**

There are four main directions as shown below

1. North

2. South

3. East

4. West

The angle between any two prime directions is 90°.

**Sub-directions/ Directions**

A direction between two main or prime directions is known as a sub-directions/directions.

There are four sub-directions as given below

1. North-East (N-E)

2. South-East (S-E)

3. South-West (S-W)

4. North-West (N-W)

The angle between any two adjacent sub-directions is 90°.

**Representation of Directions**

The various directions discussed above are represented on paper as shown below .

Angle formed between a prime direction and a sub-direction is 45°.

**Concept of Directions**

It is based on the position of the Sun. The Sun rises in the East and sets in the West.

If we face the Sun when it rises, then our position is as follows

• Direction towards our front = East

• Direction towards our back = West

• Direction towards our left hand = North

• Direction towards our right hand = South

If we face Sunset, then our position is as follows

• Direction towards our back = East

• Direction towards our front = West

• Direction towards our right hand = North

• Direction towards our left hand = South

**Concept of Turns**

**1. Left Turn (Anti-clockwise Turn)** When a person turns in a direction opposite to motion of a clock, then this turn is called left turn or anti-clockwise turn.

• When a person goes towards North from his original position and turns anti-clockwise, then it is his left.

**2. Right Turn (Clockwise Turn)** When a person takes a turn in the direction of motion of clock, then this turn is called right turn or clockwise turn.

• When a person goes towards North and turns clockwise, then it is his right.

**Concept of Shadow**

In the morning, when the Sun rises in the East, the shadow of any person or object is in the West direction. Similarly, in the evening, when the Sunsets in the West, the shadow of a person or an object is towards the East.

**Note** At 12:00 noon, there will be no shadow as the rays of the Sun are vertically downwards at that time.

Different types of questions covered in this chapter are as follows

• Finding the Distance

• Finding both the Distance and Direction

**Finding the Direction**

In this type, problems are based on the final direction of an object with respect to its starting point. It requires the knowledge of main as well as sub-directions and the angle between them.

**Example** In the morning, I walked 2 km facing the Sun and stopped. From there, I walked 4 km on my right hand side, from there I walked 1 km again facing the Sun, from there I walked on my right hand side. In which direction, I shall be walking now?

**SSC (10 + 2) 2012**

(a) East

(b) South-East

(c) South-West

(d) Right hand side

**Answer:**

**Example** At Sunrise, Amit and Deepak are having a conversation standing in front of each other. The shadow of Deepak is formed towards the right hand of Amit. What direction is Deepak facing?

(a) North-East

(b) South

(c) East

(d) North

**Answer:**

**Finding the Distance**

In this type, problems are based on the distance travelled by a person during its journey.

The distance is calculated between the starting and end points. Sometimes Pythagoras theorem is used to calculate the horizontal as well as vertical distances between the points.

According to the Pythagoras theorem, in a right angled triangle,

**Example** Anita drives from point A towards North and travels 30 km. She, then turns to her right and travels 4 km and then again turns to the right and drives straight for 30 km. How much distance she has to cover to go straight to the starting point? **SSC (10 + 2) 2011**

(a) 26 km

(b) 8 km

(c) 22 km

(d) 4 km

**Answer:**

**Example** Location of B is North of A and location of C is East of A. The distances AB and AC are 5 km and 12 km, respectively. The shortest distance (in km) between the locations B and C is

(a) 60

(b) 13

(c) 17

(d) 7

**Answer:**

**Finding both the Distance and Direction**

In this type of questions, it is asked to determine both distance and direction.

**Example** Town D is 12 km towards the North of town A. Town C is 15 km towards the West of town D. Town B is 15 km towards the West of town A. How far and in which direction is town B from town C?
