3d trigonometry gcse exam question practice

Supercharge your learning. So this means we can combine equation 1 and 2to give our 3D Pythagoras equation. With 3D Trigonometry, there is no trick, you need to solve each section in steps which makes it a harder topic.

To find missing sides or angles in 3 dimensional shapes, we need to be very clear which rules and formulae we need to use in order to find different angles and side lengths. You may need to carry out this process several times in a question to fully answer what is being asked. You must be able to justify which rule or formulae you need to use. Includes reasoning and applied questions. Calculate the length of the line AH. We can find the length of FH by using simple trigonometric ratios. Find the length of the line CE.
