# Try some yourself

## Question 1

Draw a line of symmetry on each of the shapes below.

### Answer

Each of the shapes has only one line of symmetry, so these are the only possible answers.

## Question 2

Mark all of the lines of symmetry on these shapes. For each shape, state the total number of lines of symmetry.

### Answer

## Question 3

Which of these have rotational symmetry?

### Answer

- (a) The dartboard has rotational symmetry.

- (b) The letter Z has rotational symmetry.

- (c) The letter K does not have rotational symmetry.

## Question 4

Mark the centre of rotation on each of the shapes below. For each, state the order of rotational symmetry.

### Answer

Notice that (d) has no rotational symmetry and no centre of rotation.

## Question 5

Describe the symmetry of each of these shapes. Mark all the lines of symmetry in each case. Also mark the centre of rotation, and state the order of rotational symmetry.
