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.
