PQR is isosceles right angle, right angled at Q. Prove that ​

Answer»

PR²=2PQ²Step-by-step EXPLANATION:Given:∆PQR is isosceles,PQ=QRmQ=90°To PROVE:PR²=2PQ²Proof:in ∆PQR , due to it is a right angled triangle,by PYTHAGOREAN theorem, PQ²+QR²=PR²........................................(i)due to it is a isosceles , PQ=QR......................................................(II)now,by putting the value of QR from equation (ii) in equation (i), we get,PQ²+PQ²=PR²2PQ²=PR²(proved)thank u.................please mark as brainliest
