Use as an introduction or recap to lessons on trigonometry. Discuss with students that the different trig functions are based on ratios and show this by comparing similar triangles.

The three trigonometric ratios; sine, cosine and tangent are used to calculate angles and lengths in right-angled triangles. The sine and cosine rules calculate lengths and angles in any triangle.

Using trigonometry, a person can determine the missing angle and side measurements of a right triangle based on the information present in a drawing. Although solving trigonometric ratios often ...

Solving Triangles: Candidates must be adept at solving different types of triangles using trigonometric principles. This includes both right-angled and non-right-angled triangles.
