However, an understanding of trigonometry can also be extended to non-right angle triangles to find unknown sides or angles. The Sine and Cosine rules can be applied to find any unknown side or angle ...

There are three different trigonometric ratios, \(\sin(\theta), \cos(\theta)\), and \(\tan (\theta)\). Each is defined according to a different pair of sides in the triangle. Trigonometric ratios are ...
