SSS3 Mathematics: Bearing and Distances

In this lesson students will learn about bearing and distances. Bearing can be defined as the clockwise angular movement between two distant places. Rules for Solving Bearing and Distances. 1. Taking reading in bearing starts from the North Pole in clockwise direction and ends also at the North Pole.
Objectives
At the end of the tutorial, students should be able to;
Demonstrate a clear understanding of bearings.
Calculate the magnitude and the direction of any point.
There are many situations in which you might need to describe your position and direction of travel. For example, you may tell a friend that you will meet them by the bus station, at 7pm, and that if they are late you will start walking up the high street. In mathematics, we use more precise ways to describe position and direction of travel.
Angles have many applications in our everyday lives. Builder architects for example use angles in their work. In geography angles are used to show directions. Sailors have no road to follow just a compass and a map to navigate with. Surveyors also use angles and bearing in their work. Bearing gives direction in terms of an angle.
True Bearing
The true bearing to a point is the angle measured in degrees in a clockwise direction from the north line. We will refer to the true bearing simply as the bearing.
A three figure bearing is always;
An angle measured in degrees.
Measured as angles in the clockwise direction from the geographic North.
An angle given in three figure or digit from 0000 to 3600.
Note
You use extra zeros to make the number up to three digits if you need to.
For example, 30 gives a bearing of 0030and 990 gives a bearing of 0990.
