Unit 6: Geometrical Transformations on the Cartesian Plane

Exhaustive NECTA CSEE Form 2 Basic Mathematics revision notes covering definition and classification of geometric transformations (isometries vs enlargements), reflections across axes and lines y = ±x, translations using column vectors, rotations about the origin through ±90° and 180°, enlargements with positive and negative scale factors about the origin and arbitrary centres, finding lines of reflection and centres of rotation/enlargement, non-commutativity of composite transformations, invariant points and lines, examiner pitfalls, and full NECTA practice problems with detailed marking schemes.
