###### Question 1.Construct the right angled {tex}\Delta {/tex}PQR, where {tex}m\angle {/tex}Q = {tex}{90^ \circ },{/tex} QR = 8 cm and PR = 10 cm.

To construct: A right angled triangle PQR where {tex}m\angle {/tex}Q = {tex}{90^ \circ },{/tex} QR = 8 cm and PQ = 10 cm. Steps of construction:

(a) Draw a line segment QR = 8 cm.

(b) At point Q, draw QX {tex} \bot {/tex} QR.

(c) Taking R as centre, draw an arc of radius 10 cm.

(d) This arc cuts QX at point P.

(e) Join PQ.

It is the required right angled triangle PQR.
