Question

In triangle pqr, qpr =80 and pq=pr . What is the measure of angle r and angle q ?​

Answer 1

Answer:

in a triangle the angle sum is 180 degrees,

therefore,80+r+q=180

r=q(pq=pr)

let r=q=x

80+2x=180

2x=100

x=50

r=q=50 degrees

Answer 2

Answer:

as pq=pr, so angle r=angle q

angle p+ angle q+angler=180

q+r=180-80=100

so angle q=angler=50
