\(\triangle ABC \sim \triangle LMN\) and \(BC : MN = 5 : 3\). Then
A. \(\triangle LMN\) is larger than \(\triangle ABC\)
B. the two triangles are congruent
C. the sizes cannot be compared
D. \(\triangle LMN\) is smaller than \(\triangle ABC\)

B. the two triangles are congruent
C. the sizes cannot be compared
D. \(\triangle LMN\) is smaller than \(\triangle ABC\)
Best answer
Answer: D. \(\triangle LMN\) is smaller than \(\triangle ABC\)
\(MN = \frac{3}{5} BC\), so every side of \(\triangle LMN\) is \(\frac{3}{5}\) of the corresponding side of \(\triangle ABC\). \(\triangle LMN\) is smaller.
