After studying this section, you will be able to:
- use the sine, cosine and tangent ratios to find angles and sides in right-angled triangles
- find the area of a triangle using the formula
- find the sine, cosine and tangent of any angle
- use the sine and cosine rules
The video below shows you how to find lengths or angles within a triangle using trigonometry and find out Sine, Cosine and Tangent rules.
