First we need to check the corresponding sides, they must have the same scale
[tex]\begin{gathered} EW\cong SL \\ EM\cong SH \end{gathered}[/tex]
to find the ratio of scale we make a division
[tex]\begin{gathered} \frac{EW}{SL}=\frac{EM}{SH} \\ \\ \frac{3}{5}=\frac{6}{9} \\ \\ \frac{3}{5}\ne\frac{2}{3} \end{gathered}[/tex]
the scale between corresponding sides is different, then the figures are not similar
