Understanding Three-Figure Bearings
This page provides essential information on how to measure and interpret three figure bearings in mathematics and navigation. It emphasizes key concepts and common pitfalls to avoid when working with bearings.
The page begins by introducing the concept of bearings and their measurement. It explains that bearings are always measured clockwise from north, which is a fundamental principle in navigation and mathematics.
Definition: A bearing is an angle measured clockwise from north, used to specify the direction of one point relative to another.
The guide then presents two examples of bearing measurements, illustrating both correct and incorrect interpretations. In the first example, it shows a bearing of 245°, which is correctly measured clockwise from north.
Example: A bearing of 245° is shown as the correct angle measured clockwise from north.
The second example demonstrates a common mistake in interpreting bearings. It shows an angle that, while present in the diagram, is not the correct bearing because it's not measured clockwise from north.
Highlight: Always ensure you're measuring the angle clockwise from north, even if another angle appears more prominent in the diagram.
The page concludes with two crucial points to remember when working with bearings:
- Bearings always have three digits.
- Bearings are always measured clockwise from north.
Vocabulary: Three-figure bearing - A bearing expressed using three digits, even for angles less than 100°. For example, 028° instead of 28°.
This information is particularly useful for students studying how to measure bearings with three digits at the KS2 or GCSE level. It provides a solid foundation for understanding angle measurements for bearings and prepares students for more complex bearing questions and answers in mathematics and trigonometry.
