Use graph paper for this question.
Take $1\mathrm{cm}=1$ unit on both $\mathit{x}$ and $\mathit{y}$ axes.
(i) Plot the following points on your graph sheets :
$\mathrm{A}\left(-4,0\right),\mathrm{B}\left(-3,2\right),\mathrm{C}\left(0,4\right),\mathrm{D}\left(4,1\right)$ and $\mathrm{E}\left(7,3\right)$.
(ii) Reflect the points $\mathit{B},\mathit{C},\mathit{D}$ and $\mathit{E}$ on the $\mathit{x}$ axis and name them as ${\mathit{B}}^{\prime },{\mathit{C}}^{\prime },{\mathit{D}}^{\prime }$ and ${\mathit{E}}^{\prime }$ respectively.
(iii) Join the points $\mathit{A},\mathit{B},\mathit{C},\mathit{D},\mathit{E},{\mathit{E}}^{\prime },{\mathit{D}}^{\prime },{\mathit{C}}^{\prime }$, ${\mathit{B}}^{\prime }$ and $\mathit{A}$ in order.
(iv) Name the closed figure formed.
