For Janna to prove that △ABC∼△DEF by the SSS similarity theorem, she will use: B. DE/AB = EF/BC = DF/AC = 1/4.
<h3>What is the SSS Similarity Theorem?</h3>
According to the SSS similarity theorem, if the ratio of the corresponding sides of two triangles are equal, then both triangles are similar.
The ratio of the corresponding sides of the triangles given are:
DE/AB = 4/16 = 1/4
EF/BC = 3.25/13 = 1/4
DF/AC = 1.75/7 = 1/4
Therefore, what Janna needs is:
B. DE/AB = EF/BC = DF/AC = 1/4
