GCSE Maths - What are Bearings? #118

The video tutorial explains how to use bearings, commonly used in navigation, by introducing three key rules: measuring angles from the north, measuring clockwise, and using three digits. It provides examples, including finding the bearing of point P from Q and solving an exam-style question involving bearings to locate a pond. The tutorial also addresses practical challenges, such as using a protractor to measure angles greater than 180 degrees.

What is the primary purpose of using bearings in navigation?

• To find the elevation of a point

• To measure the distance between two points

• To determine the direction from one point to another

• To calculate the speed of travel

When measuring a bearing, from which direction should you always start?

• West

• South

• East

• North

How should bearings be expressed in terms of digits?

• Two digits

• Three digits

• Four digits

• One digit

If a protractor only measures up to 180 degrees, how can you find a bearing greater than 180 degrees?

• Use a different protractor

• Double the measured angle

• Subtract the measured angle from 360

• Add 180 to the measured angle

In the example with points P and Q, what was the bearing of P from Q?

• 050 degrees

• 180 degrees

• 310 degrees

• 065 degrees

In a complex bearing problem, what is the first step after identifying the north direction?

• Estimate the angle visually

• Calculate the distance between points

• Label all points with letters

• Draw the bearings onto the diagram

In the final example, what was the bearing of the pond from person A?

• 310 degrees

• 260 degrees

• 180 degrees

• 056 degrees
