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.

e.g. Leave until the end Leave until the end
