Question

In ∆ PQR, PQ2=PR2+QR2 then state which angle Will be the right angle​

Answer 1

Answer:

$< prq = 90degree$

that's is your answer

Answer 2

The Pythagoras theorem states that the opposite angle of hypotenuse will be always right angle, that means the opposite angle of hypotenuse will be 90°,

according to the question:-

In ∆ PQR, PQ²=PR²+QR²

that means PQ is the hypotenuse of ∆ PQR

∴ ∠PRQ will be 90°

∴ it is proven that ∆ PQR is a right angled triangle

Ans:-∆ PQR is a right angled triangle
