Question

In triangle PQR, angle P = angle R. Name the pair of sides which are equal.

Plz tell me the answer. ​

Answer 1

Answer:

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.
