Answer:
ΔGHI and ΔDEF are similar by SSS criteria
Step-by-step explanation:
Consider triangle GHI and triangle DEF
In ΔGHI, GH = 2, HI =4 and GI = 3.5
In ΔDEF , DE =4, EF = 6 and DF = 7
GH/DE = 2/4 =1/2
HI/EF = 3/6 = 1/2
GI/DF = 3.5/7 = 1/2
The corresponding sides are in same ratio by SSS criteria
ΔGHI and ΔDEF are similar
