what theorem can be used to prove the 2 triangles similar?

Answer:
C. SSS
Step-by-step explanation:
[tex] \frac{AB}{SQ} = \frac{AC}{SR} = \frac{BC}{QR} = 2 [/tex]
Thus, the ratio of the corresponding side lengths of both triangles are equal. This implies that all three corresponding side lengths of both triangles are proportional to each other.
Consequently, based on the SSS Criterion, we can conclude that both triangles are similar to each other.
