Question

please solve this question ​

Answer 1

Answer:

Given, In triangle pqr angle R equal to angle P

so, triangle pqr is an isosceles triangle

Also, in an isosceles triangle opposite sides of equal angles are also equal.

So,

QR=PQ

Hence, PQ = 4 cm

Answer 2

Answer:

so, angle R= angle P

Therefore, PQ=QR

PQ= 4cm
