1B Taking it FURTHER
1. Write the missing numbers for each number line below. Then, explain how you worked out the missing values.
(i) (ii) 23 3 33 38 43 27 35 43
2. Plot the following points on a coordinate plane. A = (–4, 1)
B = (–2, –2) C = (2, –2) D = (4, 1) E = (0, 6) F = (0, 7)
(i) Using a ruler, join the points together in alphabetical order. (ii) Draw a straight line to join point F to point A, and another to join point A to point D. (iii) Is AD a line of symmetry for the shape ABCDEF? Give a reason for your answer.
3. Copy the diagram opposite. (i) Refl ect the object through the x-axis. (ii) Refl ect the object through the y-axis.
