Study Notes
Bearings are angles measured clockwise from the north direction, used in navigation and geometry. Bearings are always expressed in three digits, such as 025° or 205°.
- Bearing — an angle measured clockwise from the north direction. Example: The bearing of B from A is 025°.
- Three-digit notation — bearings are always written with three digits. Example: 3° is written as 003°.
- Trigonometric functions — used to calculate bearings and distances. Example: Using sine, cosine, or tangent to find unknown angles or distances.
Exam Tips
Key Definitions to Remember
- A bearing is an angle measured clockwise from the north direction.
- Bearings are always written in three-digit notation.
Common Confusions
- Forgetting to measure the angle clockwise from north.
