Graph $\triangle \mathrm{FGH}$ with vertices $\mathrm{F}(\square 2,2),$ $\mathrm{G}(\square 2, \square 4),$ and $\mathrm{H}(\square 4, \square 4)$ and its image after the similarity transformation. ( See Example 1.)
Translation: $(\mathrm{x}, \mathrm{y}) \rightarrow(\mathrm{x}+3, \mathrm{y}+1)$
Dilation: $(\mathrm{x}, \mathrm{y}) \rightarrow(2 \mathrm{x}, 2 \mathrm{y})$
