Level 4/5 Booster Lesson 10B Transformations

2
**Objectives: Vocabulary: angle of rotation rotation translation**

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?**

You can use tracing paper in KS3 and KS4 exams to help you rotate shapes.

9
**Here is a shape it has been rotated**

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: Vocabulary: angle of rotation rotation translation**

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**
