The triangles shown are similar. Which side of triangle PQR corresponds to side LN in triangle MNL? Triangle L N P. Side L N is
Lerok [7]

Answer:

LN corresponds to RQ

Step-by-step explanation:

If we look at the diagram we find that LN corresponds to RQ, MN corresponds to QP and ML corresponds to PR .

The both triangles are similar as PQR is 2 times of MNL .

Therefore

PQR= 2MNL

PR= 2ML

28= 2(14)

QP= 2MN

20 = 2(10)

RQ =2 LN

24= 2(12)
