Direction Sense – Pictorial Explanation

Direction Sense

Hello Readers

Today’s topic is Direction Sense.

 

We will discuss concepts related to direction sense. Generally, in direction sense, two types of questions come in the examinations –

  • Distance between the two given points
  • Direction of one point from other point

 

To solve these types of questions, we must know the different types of directions.

 

Let’s see how many Types of directions – Direction Sense are –

Now, we will discuss different types of questions which are generally asked in the examinations with the help of examples –

 

Example – 1

X starts from point A and runs 10 km towards North. He takes right turn and runs 15 km. He now runs 6 km after taking a left turn. He finally takes a left turn, runs 15 km and stops at point B.

1) How far is point B from point A?

2) Towards which direction was X moving before it stops at point B?

3) In which direction is point B with respect to point A?

 

Solution –

 

Direction Sense 1

 

1) How far is point B from point A?

 

Direction Sense 1a

 

Distance = (10 + 6) km = 16 km

 

2) Towards which direction was X moving before it stops at point B?

 

Solution – West Direction

 

Direction Sense 1b

 

3) In which direction is point B with respect to point A?

 

Solution – North Direction

 

Direction Sense 1c

 

Example 2

A bus started moving towards west and stopped at Point X after covering 10 km. It then takes a right turn and stopped at Point Y after covering 12 km. Finally it takes a left turn, covers 6 km and stops at point Z. What is the distance between the starting point and stopping point?

 

Solution –

 

Direction Sense 2

 

Note – In this case, we have to find the slanting distance between two points. So, to find slanting distance we use Pythagoras Theorem –

 

Direction Sense EX 2

 

Example 3

If at 3 pm, the shadow of a person is on his right, then which direction is the person facing?

 

Solution –

This example is based on Shadows. So let’s first understand this concept and then we will solve this example.

To understand this concept, we must understand that how direction of shadow changes with the change in direction of sun.

 

Direction Sense shadow

 

Now, let’s solve the example –

 

Direction Sense 3

 

So, the person is facing north.

 

With this, we will finish this topic here.
