Answer:
(3)
Step-by-step explanation:
The congruence statement tells you which vertices are corresponding:
L to R
M to Q
P to N
These correspondences can be used to evaluate the proposed statements.
(1) LM and PM are segments in the same triangle; not congruent
(2) MP ≅ QN, not congruent to QR
(3) ∠RNQ ≅ ∠LPM
(4) ∠MLP ≅ ∠QRN, not congruent to ∠QNR
