Question

)Two triangles, ΔPQR and ΔLMN, are such that ∠PQR = ∠LMN and ∠QRP = ∠MNL.Which of these is NOT a sufficient condition for proving ΔPQR is congruent to ΔLMN?
(i) PQ = LM (ii) PR = LN (iii) QR = MN

only (i)
either (i) or (ii)
either (i) or (ii) or (iii)
(Any of (i), (ii) and (iii) is a sufficient condition to prove ΔPQR ≅ ΔLMN.)

Answer 1

Answer:

mark me as brainlist

Step-by-step explanation:

In △PQR and △LMN

⇒  PQ=QR and QR=LN

∴    PQ=LN

⇒  ∠P=∠M

⇒  Here, only one side and one angle are equal, so these both triangle cannot be congruent.

⇒  Two angles in both triangles are also not equal so, triangles are not isosceles.

∴   Correct answer is option D.
