Answer:
To construct: A right angled △PQR where m∠Q=90
o
, QR=8cm and PR=10cm.
Steps of construction:
(a) Draw a line segment QR=8cm
(b) At point Q, draw QX⊥QR
(c) Taking R as centre, draw an arc of radius 10cm
(d) This arc cuts QX at point P
(e) Join PQ
It is the required right angled triangle PQR
