Trigonometry is a branch of Mathematics concerned with calculation of angles and lengths of sides of triangles. It has applications in subjects including Physics, Chemistry, Engineering, Architecture, navigation and many others. The origins of trigonometry lie in the calculation of astronomical data. The earliest record of the subject comes from around 150BC in tables written by the astronomer Hipparchus of Nicaea.

The questions in this section deal only with right angled triangles.
