The points A(4,3), B(−2,3), C(−2,−5) and D(4,−5) are given on the Cartesian plane.
(i) Plot the points A, B, C and D accurately on a Cartesian plane.
(ii) State the quadrant or axis on which each point lies.
(iii) Join the points in the order A→B→C→D→A. Name the figure obtained.
(iv) Explain, using only the coordinates, why the opposite sides of the figure obtained in part (iii) are parallel to the coordinate axes.
