Vectors can be used to describe
translations – that is, when a shape is
moved in a straight line without reflecting
or rotating.

Now it’s your turn…
• On your worksheet, translate every shape
in by the vector attached to it.
• Use tracing paper to help you.
• All the shapes should fit together to form a
word.
• Draw in pencil in case you make any
mistakes.
• Count carefully!
e.g.
Now it’s your turn…
• On your worksheet, reflect every shape in
the corresponding mirror line.
• Use tracing paper to help you.
• All the shapes should fit together to form a
word.
• Draw in pencil in case you make any
mistakes.
e.g.
Now it’s your turn…
• On your worksheet, rotate every shape
according to the instructions on the shape.
• Not every point is used.
• Use tracing paper to help you.
• All the shapes should fit together to form a word.
• Draw in pencil in case you make any mistakes.
• Please note – direction is not important if the
angle is 1800.
e.g.
Now it’s your turn…
• On your worksheet, enlarge every shape
according to the instructions on the shape.
(sf stands for scale factor)
• All the shapes should fit together to form a
word.
• Draw in pencil in case you make any
mistakes.
• Leave the negative scale factors until the
end.
