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.
