5.2
Transformation geometry
Translations, rotations, reflections, enlargements.
Syllabus Statements
- 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
- Construct a mirror line given an object and reflect a shape given a mirror line
- 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
- Understand that enlargements preserve angles and not lengths
- Enlarge a shape given the scale factor
- Identify and give complete descriptions of transformations
