IGCSE Maths Edexcel A 4MA1

understand that rotations are specified by a centre and an angle

rotate a shape about a point through a given angle

recognise that an anti-clockwise rotation is a positive angle of rotation and a clockwise rotation is a negative angle of rotation

understand that reflections are specified by a mirror line

Such as $x = 1$, $y = 2$, $y = x$, $y - x = 0$

construct a mirror line given an object and reflect a shape given a mirror line

e.g. reflect a triangle in the line $y = x$

understand that translations are specified by a distance and direction

translate a shape

understand and use column vectors in translations

understand that rotations, reflections and translations preserve length and angle so that a transformed shape under any of these transformations remains congruent to the original shape

understand that enlargements are specified by a centre and a scale factor

Positive scale factor only (including fractions)

understand that enlargements preserve angles and not lengths

enlarge a shape given the scale factor

With or without a centre given

identify and give complete descriptions of transformations
