Question

PQR is a triangle, right angled at P. If PQ = 8 cm and PR = 6 cm, find QR.

Answer 1

Given , pq = 8cm pr=6cm

By using Pythagoras therom,

PQ^2=PR^2+QR^2

QR^2= 8SQUARE - 6CM

QR^2 = 64-36

QR= ROOT 28

Answer 2

Answer:

triangle PQR is right angled triangle

by pythagoras theorem

PQ ² + PR ² = QR ²

(8)² + (6)² = QR²

64 + 36 = QR ²

100 = QR²

QR = 10
