When a person asks for any address, how do we help him explainig the address? We will use the words like go straight, right, left, turn, north, east, west, south, back etc. What are all these? These are some of the direction senses and terms used to locate an object or a location.
In logical reasoning, we are given some problems based on the direction and the distance between them. The real question arises as to how to find the correct solution for these direction reasoning problems? Lets practice some questions based on direction to get proper idea about the concept.
Formula's for Direction
- There are four main directions: North (N), East (E), West (W), South(S)
- There are Four Cardinal Directions as shown in the diagram:
North-East (NE), North-West (NW), South-East (SE), South-West (SW)
Angle between North and East is 90’(Clockwise)
Angle between North and Northeast is 45’(Clockwise)
Morning (or) Sunrise (or) Dawn – WEST
Evening (or) Sunset (or) Dusk – EAST
Some Important Points:
1. At the time of sunrise if a man stands facing the east, his shadow will be towards west.
2. At the time of sunset the shadow of an object is always in the east.
3. If a man stands facing the North, at the time of sunrise his shadow will be towards his left and at the time of sunset it will be towards his right.
4. At 12:00 noon, the rays of the sun are vertically downward hence there will be no shadow.
Types of Problems:
Shadow Based Problems
- Noon – No Shadow
