Question

1. In ∆PQR, PQ = QR and ∠R = 50°, then find the measure of ∠Q
​

Answer 1

ANSWER

given thatPQ=PR

∠PQR=∠PRQ

Because we know that angles opposite to equal sides are equal

∴∠Q=∠R

given that ∠R=50

∘

∴∠Q=50

∘

Answer 2

Answer:

In Triangle PQR ,

PQ = QR

therefore triangle PQR is an isoceles Triangle !

= PQ = QR

therefore angle R = Q

( angles opposite to same side are equal )

= angle Q = 50`
