उत्तर
Steps of Construction:
(i) Draw a line segment QR = 4.4 cm.
(ii) At Q, draw a ray making an angle of 75°
(iii) At R, draw another arc making an angle of 30°; which intersects the first ray at R
∆ PQR is the required triangle.
On measuring the lengths of PQ and PR, PQ = 2.1 cm and PR = 4. 4 cm.
