  1. Level 4/5 Booster Lesson 10B Transformations

  2. Objectives: • Recognise and visualise transformations – reflection, rotation and translation. Vocabulary: angle of rotation rotation translation reflection vector centre of rotation

  3. For each of the shapes below find their lines of symmetry: W/S 10.1B

  4. Did you find them all? The parallelogram has no lines of symmetry – make a parallelogram from paper and try folding if you are not convinced.

  5. For each of the shapes below draw the reflection in the mirror line given: W/S 10.2B

  6. Did you reflect the shapes correctly? In exams at KS3 and KS4 you can use tracing paper to help you with questions about reflection.

  7. Using the centre C can you rotate this triangle 90º clockwise? Using centre C can you rotate this rectangle 180º clockwise? C C Using centre C can you rotate this rhombus 90º clockwise? Using centre C can you rotate this arrowhead 90º anti-clockwise? C W/S 10.3B

  8. Did you rotate the shapes correctly? C C C You can use tracing paper in KS3 and KS4 exams to help you rotate shapes.

  9. Here is a shape it has been rotated. Can you find the centre and the angle of rotation? Here is a shape that has been rotated can you find the centre and the angle of rotation? W/S 10.4B

  10. The centre of the rotation stays the same so the centre is the corner that has not moved. This shape has been rotated 180º (clockwise or anticlockwise). C C The shape has been rotated through 90º clockwise

  11. The triangle labelled A has been translated into positions B, C, D and E. Can You describe each of these transformations using a vector? B C A Example: A B is a translation 3 2 E D 3 squares along and 2 squares up

  12. Here are the correct answers: B 3 2 A B Translation C A C - 2 1 A Translation E 1 - 3 A D Translation D • 1 • - 2 A E Translation

  13. Task: Draw a 1 by 2 right-angled triangle in different positions and orientations on 5 by 5 spotty paper. Choose one of the triangles to be the original. Describe fully the transformations from your original to each of the other triangles drawn. You need W/S 10.5B

  14. Objectives: • Recognise and visualise transformations – reflection, rotation and translation. Vocabulary: angle of rotation rotation translation reflection vector centre of rotation

  15. Thank you for your attention
