MATHS - Geometry - Bearings Maps and Scale Drawings

The video tutorial explains bearings, which are used to describe directions measured clockwise from north. It covers how to measure bearings between locations, using examples and scenarios involving navigation, Pythagoras' theorem, and trigonometry. The tutorial emphasizes the importance of three-digit bearings and provides practical tips for measuring angles without a 360-degree protractor. It concludes with a summary of key points and a reminder of the significance of bearings in navigation.

What is the correct way to express a bearing of 45 degrees?

• 450 degrees

• 0045 degrees

• 045 degrees

• 45 degrees

If you don't have a 360-degree protractor, how can you measure a bearing of 209 degrees?

• Measure 29 degrees from the north line

• Measure 29 degrees from the south line

• Measure 151 degrees from the south line

• Measure 151 degrees from the north line

A ship is on a bearing of 117 degrees from town A and 209 degrees from town B. How do you find its location?

• Calculate the average of the two bearings.

• Draw a line from town A at 117 degrees and from town B at 209 degrees; the intersection is the location.

• Measure the distance between town A and town B.

• Use a compass to find the midpoint between the two towns.

In a right triangle formed by bearings, if one side is 3 km and the hypotenuse is 6 km, what is the angle opposite the 3 km side?

• 60 degrees

• 90 degrees

• 45 degrees

• 30 degrees

What is the bearing of town A from town C if the angle BCA is 30 degrees?

• 30 degrees

• 300 degrees

• 60 degrees

• 330 degrees
