Trigonometry in Bearing Calculations

This section introduces trigonometry into bearing questions GCSE with answers, combining bearing concepts with trigonometric calculations. These problems represent higher exam questions with trigonometry.

Example: Question 10 involves calculating the bearing of C from A, given that C is due south of B and other angle information is provided.

Highlight: These questions require students to apply trigonometric ratios and the properties of isosceles triangles to solve bearing problems.

Vocabulary: Isosceles triangle - A triangle with two sides of equal length and two angles of equal measure.

View

Bearing Calculations with Multiple Points

This page focuses on more challenging GCSE bearings questions and answers, involving calculations with multiple towns or points. These questions require a deeper understanding of bearing relationships and angle calculations.

Example: Question 7 asks to find the bearing of B from A, given that the bearing of A from B is 225°.

Highlight: These problems introduce the concept of working backwards from given bearings to find reverse bearings, an essential skill for more complex bearing calculations.

Vocabulary: Reverse bearing - The bearing from point B to A when the bearing from A to B is known.
