Bearings and Trigonometry

What are Bearings in maths?

• A bearing is an angle, measured clockwise from the north direction.

• A bearing is an angle, measured counter - clockwise from the north direction.

• A bearing is an angle, measured clockwise from the east direction.

• A bearing is an angle, measured counter - clockwise from the east direction.

• Any normal angle

How do you measure a bearing?

• Mark North and use a protractor

• Mark East and use a protractor

• Mark North. Using a pair of compass, make a perpendicular bisector measuring 90 degrees. Make any two random bisectors and the point where they meet is the measure.

• Mark East. Using a pair of compass, make a perpendicular bisector measuring 90 degrees. Make any two random bisectors and the point where they meet is the measure.

What is the measure of the angle with a Bearing of 45 degrees?

• 315 degrees counter - clockwise

• 45 degrees clockwise

• 135 degrees clockwise

• 45 degrees counter - clockwise
