True and Compass Bearings

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.
