Question

6. Angles Q and R of a APQR are 25º and 65°
Write which of the following is true:
(1) PQ2 + QR2 = RP2
(ii) PQ2 + RP2 = QR?
(iii) RP2 + QR2 = PQ2
(​

Answer 1

Answer:

1. option is right. .......

Answer 2

Answer:

option 2 is right

Step-by-step explanation:

since angle Q and angle R of the triangle are 25° and 65° respectively

therefore,

angle P = 180 -25 -65 [ ASP of Triangle ]

angle P = 90°

so it is a right triangle

So, QR is the hypotenuse as it is the side opposite to right angle

By pythagoras theorem,

QR² = PR² + RP²
