Question

in figure angle PQR f​

Answer 1

Answer:

Given:

Angle PQR = 85°

Angles PQR and PTR have the same intercepts in the arc PMR.

Solution:

As per theorem, angles having the same base points on the circumference of the circle and having their vertices on the circumference are always equal.

For angles PQR and PTR, they have the same base points P and R in the circumference of the circle and their vertices Q and T are on the circumference of the same circle.

Therefore,

Angle PQR = Angle PTR = 85°

Thus, the value of angle PTR is 85°.
