Discovering Trigonometry (Investigation) WORKSHEET
Suitable for Year groups: Year 8, Year 9
GCSE Tier: Foundation/Higher
Targeting grades: 4-5
Prerequisite knowledge: Measuring lengths and angles, arithmetic, using a calculator.
Learning Objective: Discover the relationships between the ratios of side lengths in similar right angle triangles
Discovering Trigonometry (Investigation) WORKSHEET DESCRIPTION
This worksheet is designed to provide an opportunity for learners to discover the relationships between the side lengths of right-angle triangles and the trigonometric ratios sin, cos and tan.
The first three sections provide sets of similar triangles for learners to measure the specified lengths and angles and then compare the ratios of the chosen sides with the relevant trig function. The remaining sections are helpful to consolidate which side lengths match to which trig function.
All worksheets are created by the team of experienced teachers at Cazoom Maths.
