Bearings in Maths

This video tutorial explains bearings, a measure of direction using angles from 0° to 360°, and their calculation. Bearings are crucial for navigation, starting from north and measured clockwise. The video covers calculating bearings with a protractor, finding reverse bearings using angle properties, and locating objects using intersecting bearings. Key points include using three-digit angles, starting from north, and applying angle rules. A practice question is provided for reinforcement.

What is the starting point for measuring bearings?

• South

• East

• West

• North

How are bearings typically written?

• Using one digit

• Using four digits

• Using three digits

• Using two digits

When measuring a bearing, in which direction should you turn?

• Upwards

• Clockwise

• Counterclockwise

• Downwards

If you don't have a protractor, which angle property can help you find a bearing?

• Complementary angles

• Vertical angles

• Alternate angles

• Supplementary angles

What is the reverse bearing of 258°?

• 198°

• 102°

• 258°

• 78°

How can you find the exact location of an object using bearings?

• By measuring the distance

• By drawing a single line

• By extending lines from two points until they intersect

• By using a compass

Which of the following is a key point to remember when working with bearings?

• Bearings are written using two figures

• Always measure from the south

• Use your knowledge of angle properties

• Bearings are measured counterclockwise
