Use graph sheet to answer this question. Take $2 \mathrm{cm}=1$ unit along both the axes. (a) Plot $A, B, C$ where $A(0,4), B(1,1)$ and $C$ $(4,0)$ (b) Reflect $A$ and $B$ on the $x$-axis and name them as $E$ and $D$ respectively. (c) Reflect $B$ through the origin and name it $F$. Write down the coordinates of $F$. (d) Reflect $B$ and $C$ on the $y$-axis and name them as $H$ and $G$ respectively. (e) Join points $A, B, C, D, E, F, G, H$ and $A$ in order and name the closed figure formed.
