Question

1. which property of similarity can be used to prove triangles def and ghi are similar? not enough information aa sas sss

Explanation:

Step1: Check side - length ratios

Calculate the ratios of corresponding sides: $\frac{DE}{GH}=\frac{9}{13.5}=\frac{2}{3}$, $\frac{EF}{HI}=\frac{7}{10.5}=\frac{2}{3}$, $\frac{DF}{GI}=\frac{12}{18}=\frac{2}{3}$.

Step2: Apply similarity criterion

Since the ratios of all three pairs of corresponding sides are equal, by the SSS (Side - Side - Side) similarity criterion, the two triangles are similar.

Answer:

SSS
