Answer :

In the above question, it is given that:

In PQR, we have

Q = 25o and R = 65o

We know that,

The sum of interior angles of a triangle = 180o

PQR + PRQ + QPR = 180o

25o + 65o + QPR = 180o

90o + QPR = 180o

QPR = 180o – 90o

= 90o

Hence, is right angled at point P

Thus,

By using Pythagoras theorem, we get:

(PR)2 + (PQ)2 = (QR)2

Hence,

Option (ii) is true
