Use a graph paper for this question. Take 2 cm = 1 unit along both the axes.
(i) Plot the points A(0, 4), B(2, 2), C(5, 2) and D(4, 0). E(0, 0) is the origin.
(ii) Reflect B, C, D on the y-axis and name them as B', C' and D' respectively.
(iii) Join the points ABCD D'C'B' and A in order and give a geometrical name to the closed figure.

Answer
(i) The point A(0, 4), B(2, 2), C(5, 2) and D(4, 0), E(0, 0) are plotted on the graph below :
(ii) From graph, on reflecting B, C, D on y-axis we get,
⇒ B(2, 2) ⇒ B'(-2, 2)
⇒ C(5, 2) ⇒ C'(-5, 2)
⇒ D(4, 0) ⇒ D'(-4, 0).
(iii) Join the points ABCD D'C'B'A.
Hence, the figure formed is a boat.
