Let

p, q

and

r

be the sides opposite to the angles

P, Q

and

R

, respectively in a

\triangle P Q R

. If

r^2 \sin P \sin Q=p q

, then the triangle is

View answer and explanation

Correct option: D

right angled

Option D (right angled) is correct because the given condition simplifies to

\sin^2 R = 1

, implying

R = 90^{\circ}
