Question
Use graph paper to answer the following questions. (Take 2 cm = 1 unit on both axis).
(i) Plot the points A (- 4, 2) and B (2, 4).
(ii) A’ is the image of A when reflected in the y-axis. Plot it on the graph paper and write the coordinates of A’.
(iii) B’ is the image of B when reflected in the line AA’. Write the coordinates of B’.
(iv) Write the geometric name of the figure ABA’B’.
(v) Name a line of symmetry of the figure formed.

Answer

(i) On the graph.
(ii) Co-ordinates of A' = (4, 2).
(iii) Co-ordinates of B' = (2, 0).
(iv) Geometric name of Fig. ABA'B' is kite.
(v) Line of symmetry = AA'.
