SOLUTION
If triangle QRS and TUV are similar, then
[tex]\begin{gathered} \frac{QR}{TU}=\frac{RS}{UV}=\frac{QS}{TV} \\ \\ \frac{15}{75}=\frac{16}{80}=\frac{18}{90} \end{gathered}[/tex]
So let's check
[tex]\begin{gathered} \frac{15}{75}=0.2 \\ \\ \frac{16}{80}=0.2 \\ \\ \frac{18}{90}=0.2 \end{gathered}[/tex]
Therefore, the triangles QRS and TUV are similar
SSS- three sides proportionate
