Question

please help me out ​

Answer 1

Step-by-step explanation:

$heloo.... \\ \\ since \: its \: isosceles \: right \: triangle = >$

PQ = QR..........(1)

Now using Phytagores theorem

PR^2 = PQ^2 + QR^2

PR^2 = 2(PQ) ^2........ (as PQ = QR)

Hope it helps uh!!!!!

Answer 2

Answer:

Given that

the given triangle is isosceles

means any two sides are equal

so,

in triangle PQR

Apply Pythagoras theorem we get

PR² = PQ² + QR²

PR² = PQ² + PQ² ------(Since given triangle is isosceles)

PR² = 2PQ²

Hence Prooved

Hope it will help you
