Direction Sense Concept by | Engineer Ji | General Intelligence | Part I

Main Directions:

• There are four main Direction's: North, South, East, West
• Angle between any two prime directions is 90°

Sub-Directions:

• A direction between two main or prime directions is known as a sub-directions.
• There are four sub-directions: North-East, South-East, South-West, North-West.
• The angle between any two adjacent sub-directions is 90°
• The angle formed between a prime direction & a sub-direction is 45°
• The concept of Directions: 
• It is based on the position of the Sun. the Sun rises in the East & sets in the West.

i). If we face the Sun when it rises, then our position is as follows:

ii). If we face Sunset, then our position is as follows: 

The concept of Turns:

1). Left Turns (Anti-Clockwise):

• When a person turns in a direction opposite to the 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 & turns anti-clockwise, then it is his left.

2). Right Turns (Clockwise):

• 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 & turns clockwise, then it is his right.

The 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 PM noon, there will be no shadow as the rays of the Sun are vertically downwards at that time.

Type of Questions in This section:

i). 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 & the angle between them.

E.g.; In the morning, I walked 2km facing the Sun and stopped. From there, I walked 4km on my right-hand side, from there I walked 1km again facing the Sun, from there I walked on my right-hand side. In which direction. I shall be walking now?
i). East
ii). South-East
iii). South-West
iv). Right-hand side
