Question

In traingle PQR , PQ = PR and angle R=40, then angle Q =​

Answer 1

Answer:

qp=pr

implies angleR=anglep

applying sum of all angles is 180

we get angleQ= 100 degree

Answer 2

In triangle PQR, we have ,PQ = PR

This implies that angle PQR = angle PRQ

(since angles opposite to equal sides are equal)

that is angle Q = angle R

Therefore,Angle Q = 40 degrees

(since angle R = 40 degrees (given) )
