Transformation Geometry
Bayani Gaba-gaba
Transformations move, flip, turn or resize shapes on the coordinate plane. Understanding the four types and being able to describe them fully is a core Edexcel skill that appears frequently on both papers.
You will learn to perform and describe reflections, rotations, translations and enlargements. Three of these preserve the size of the shape (producing a congruent image), while enlargement changes the size (producing a similar image).
Manufura
- 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
