Question

If. LM=qr ,mn=pr and nl=pq

Answer 1

Sorry but you didn't clarify your question.

Please make sure to ask properly before sending.

In ∆LMN and ∆QRP,

LM=QR (given)

MN=PR (given)

NL=PQ (given)

then, ∆LMN ~ ∆QRP [SSS SIMILARLY RULE]

THEREFORE,

∠N=∠P, ∠L=∠Q, ∠M=∠R [reason: corresponding sides of similar ∆s are equal]

Hope it helps.
