GCSE Mathematics Targeting Grade C Shape and Space Unit 6 Transformations
If not you need • Can you ... • Understand the 4 transformations • Understand Reflection • Understand Rotation • Try a test • Understand Enlargement • Understand Translation • Try a test TOPThe 4 transformations Practice 1Reflection Practice 2: Rotation TAIL 1 Practice 3: Enlargement Practice 4: Translation TAIL 2
TOP Remember: There are 4 different types of transformations Reflection – (mirror image) requires a mirror line, line of symmetry or equation of the line of symmetry Rotation – shape turns round but stays the same size; requires the degree and direction of the rotation with a point which is the centre of rotation Enlargement – shape changes size (smaller or larger); requires a scale factor and sometimes a centre of enlargement Translation – this is simply a shift and requires number of units to be moved left/right and up/down Lesson
Practice 1: Reflection 1. Reflect the triangle in the x-axis. (Total 1 mark) Next
