Question

Are these triangles similar if they are what is the scale factor that takes EFGH to ABCD?

Answer 1

`\begin{array}{llll} \cfrac{CD}{DA}\implies \cfrac{5}{25}\implies \cfrac{1}{5} \\\\\\ \cfrac{GH}{HE}\implies \cfrac{3}{5}\implies \cfrac{1}{5} \end{array}\qquad \begin{array}{llll} \textit{corresponding sides have the same ratio}\\ \textit{similar rectangles}\\ \textit{scale factor of }\cfrac{1}{5} \end{array}`
