Bearings

By: Rachel Raaga RameshG8

Angle made in clockwise direction with respect to the North is called a bearing.

Usually, for bearings measurement, a 360o

protractor is used. Bearings tell is in what direction something

is. In bearings, angles are always measured

from the North

Introduction

Measuring Bearings In this case, there are two

points given (A and B). Q: Find the bearing of A from B First, you take your protractor,

and make a 90o line upwards. Then going clockwise, measure the angle till it reaches the point on line A.

This angle is called bearing.

Example 2 The same way, in this case, there are two

points given (A and B). Q: Find the bearing of A from B Here, the measurement of angle B is given.

Since it is angles on a line, they sum up to 180o

Therefore, 180o - 46o =134 o

The bearing of A from B is 134 o

Example 3 Q: Find the bearing of: -A from B -B from A Ans 1: 205 o

Ans 2: 25 o

Example 4 Q: Find the bearing of P from O

Ans: 225 o

From the north we move clockwise and measure the angle formed.
