Direction Tests

**Objective**

After going through this lesson, you shall be able to understand the concept of direction and distance.

**Introduction**

In this lesson, we will study about the questions related to direction and distance. Such questions are meant to judge the students's ability to sense the directions correctly.

**Direction:** To slove these types of questions one must have the basic knowledge of direction. The following figure shows the four main directions and four cardinal directions

**Main Directions**

- North
- South
- East
- West

**Cardinal Directions**

- North west
- North east
- South west
- South east

**Clockwise Direction:**When something is moving in the same direction as the hands of the clock

**Anticlockwise Direction:**When something is moving in the opposite direction as the hands of the clock

**Distance:**The other main part of these questions is distance. So, one also must have the basic knowledge of geometry, such as

**Pythagoras theorem**.

**Pythagoras theorem:**

We have the following relationship between the sides of a right-angled triangle ABC.

(AC)^{2 }= (AB)^{2} + (BC)^{2}

This relation between the sides of a right-angled triangle is known as **Pythagoras Theorem.**

__Geeta starts walking facing north. After walking a distance of 8 km, she turns left and walks 6 km. How far and in which direction is she from her starting point?__
