3For each of the shapes below find their lines of symmetry: W/S 10.1B
4Did you find them all?The parallelogram has no lines of symmetry – make a parallelogram from paper and try folding if you are not convinced.
5For each of the shapes below draw the reflection in the mirror line given: W/S 10.2B
6Did you reflect the shapes correctly? In exams at KS3 and KS4 you can use tracing paper to help you with questions about reflection.
7Using the centre C can you rotate this triangle 90º clockwise? Using centre C can you rotate this rectangle 180º clockwise?CCUsing centre C can you rotate this rhombus 90º clockwise?Using centre C can you rotate this arrowhead 90º anti-clockwise?CW/S 10.3B
8Did you rotate the shapes correctly? You can use tracing paper in KS3 and KS4 exams to help you rotate shapes.
9Here 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
10The 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).CCThe shape has been rotated through 90º clockwise
11The triangle labelled A has been translated into positions B, C, D and E. Can You describe each of these transformations using a vector?BCAExample:A B is a translation32ED3 squares along and 2 squares up
12Here are the correct answers: B32ABTranslationCAC- 21ATranslationE1- 3ADTranslationD1- 2AETranslation
13Task: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
