Direction Sense Test in Reasoning

Direction sense is a very famous category of questions in competitive exams. In this category, questions are mostly focussed on directions and distance.

Here are a few concepts which you need to know before you can attempt any practice questions in this category.

Tips for Direction Sense Test in Reasoning Exams

1. 4 Main Directions

There are 4 main directions. Check the Diagram below.

2. 4 Cardinal Directions

Apart from these 4 directions, there are 4 more directions which are a mixture of above 4, they are also called cardinal directions.

3. Left – Right of Directions

There will be often questions like the following

Q. Shikhar starts walking from his home walks 8 km towards East, and then he turns right and goes 6 km. He turns right again and goes 8 km. What is the direction in which Shikhar is standing currently from his home? How far is Shikhar standing from his home?

How will you solve this problem? Bring the following figure in your mind.

This diagram will give you the right direction to solve this problem.

4. Shadows with Directions

Imagine this question came up in your next exam.

Q. Rohit is facing towards the NORTH. At sunrise where will his shadow be? And if he is facing SOUTH. Then where will his shadow be?

How will you solve these questions? With one simple concept,

Sun rises in the east, and Sun sets in the west.

and

Shadow is always opposite to the source of light (Sun)

which means

When sun rises (in morning time), sun will be in the east direction and shadow will be in the west direction

Also

When sun is about to set (in evening time), sun will be in the west direction and the shadow will be in the east direction.

5. Pythagoras Theorem

Pythagoras Theorem comes into action when there is a triangle and one of the angles of the triangle is a right angle (90°).

You can guess from the first diagram above, that when you change direction from North to East, North to West, you take 90° turn because the main directions are at 90° from each other.

You still don’t understand why this theorem is important here. Look at the question below.

Q. Virat starts walking from his home walks 4 km towards East, and then he turns right and goes 3 km. How far is Virat standing from his home?

Clearly you need to find the value of x. So check the Pythagoras theorem here.

In a right-angled triangle, If x denotes the length of the hypotenuse, and a and b are other 2 sides, then Pythagorean theorem states that
