Trigonometry
This resource is designed as a resource bank of questions to supplement the teaching element of the lesson. The questions require students to use Pythagoras' theorem in order to find whether a triangle is right angled and find the lengths of missing sides, and problems on 2D and 3D shapes.
The next section provides an array of examples requiring students to use sine, cosine and tangent to find missing sides and angles in right-angled triangles. Worded questions set in context, questions using compound shapes and questions in 3D are provided.
Questions relating to the graphs of the sine and cosine function are followed by questions requiring students to find the area of triangles using the formula: Area = 0.5 ab Sin C.
The sine rule and the cosine rule are used in the next section followed by tasks relating to the trigonometry of circumscribed circles, inscribed circles, escribed circles and using Heron's rule to find the area of a triangle.
