This eBook introduces the related subjects of Pythagoras' theorem, trigonometry and similarity, as Pythagoras' theorem relates to all right-angles triangles, trigonometry as it relates to angles and ratios of sine, cosine and tangent in right-angled triangles, angles of elevation and depression as well as similarity and congruence.This eBook is part of our range of Key Stage 3 (KS3) maths eBooks that are fully aligned with the UK Governments national curriculum.Our Key Stage 3 (KS3) maths eBooks comprise three principle sections. These are, notably:

Number and Algebra

Geometry and Measures

Handling DataIn addition, there exists a Publications Guide.Our maths eBooks are produced such as that as well as a Publications Guide, and three principle publications corresponding to the principle sections (Number and Algebra, Geometry and Measures and Handling Data) there are individual modules produced within each principle section which are published as eBooks.Pythagoras' Theorem, Trigonometry and Similarity is a module within the Number and Algebra principle section our Key Stage 3 (KS3) publications. It is one module out of a total of seven modules in that principle section, the others being:

2D Shapes and 3D Solids

Loci, Constructions and 3D Co-ordinates

Angles, Bearings and Scale Drawings

Transformations

Measures and Measurements
