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.

e.g.

If REFLECTION:FLIPPING,what is TRANSLATION?

• sliding

Translate the shapes by the corresponding vector to form a letter. Which letter is it?

What is the direction of the top number?

• right

3

7

What is the direction of the bottom number?

• down

3

7

Translate the shapes by the corresponding vector to form a letter. Which letter is it?

Translate the shapes by the corresponding vector to form a letter. Which letter is it?

Translate the shapes by the corresponding vector to form a letter. Which letter is it?

What is the rule of the given transformation?

• 2 right then 3 down

What is the rule of the given transformation?

• 3 right then 2 down

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.

If REFLECTION:FLIPPING,TRANSLATION: SLIDING,
