Question

Determine if triangle QRS and triangle TUV are or are not similar

Answer 1

If triangle QRS and TUV are similar, then

`\begin{gathered} (QR)/(TU)=(RS)/(UV)=(QS)/(TV) \\ \\ (15)/(75)=(16)/(80)=(18)/(90) \end{gathered}`

So let's check

`\begin{gathered} (15)/(75)=0.2 \\ \\ (16)/(80)=0.2 \\ \\ (18)/(90)=0.2 \end{gathered}`

Therefore, the triangles QRS and TUV are similar

SSS- three sides proportionate
