Complete the following table :
Point Transformation Image
(a) (5, -7)-------------------------------(-5, 7)
(b) (4, 2) Reflection x-axis ---------
(c) --------- Reflection in y-axis (0, 6)
(d) (6, -6) ----------------- (-6, 6)
(e) (4, -8) ------------------ (-4, -8)
(i) Point P (a, b) is reflected in the x-axis to P' (5, -2). Write down the values of a and b.
(ii) P" is the image of P when reflected in the y-axis. Write down the co-ordinates of P".
(iii) Name a single transformation that maps P' to P".
Draw a square whose vertices are (2,2), (4,2), (4,4) and (2,4). Reflect the square in the y-axis and then reflect the image in the origin. What single transformation would give the same result?
