प्रश्न
Construct the right angled ΔPQR, where m∠Q = 90°, QR = 8 cm and PR = 10 cm.
उत्तर
A rough sketch of ΔPQR is as follows.
The steps of construction are as follows.
1) Draw a line segment QR of length 8 cm.
2) At point Q, draw a ray QX making 90º with QR.
3) Taking R as centre, draw an arc of 10 cm radius to intersect ray QX at point P.
4) Join P to R. ΔPQR is the required right-angled triangle
