Question

construct a triangle pqr in which qr equal to 8centimetre and angle q equal to 45 degree and PQ-QR equal to 3.5 centimetre

Answer 1

Following steps will be followed to draw the required triangle Step I: Draw the line segment QR = 8 cm and at point Q make an angle of 45° say angle XQR.    

Step II: Cut the line segment QD = 3.5 cm (equal to PQ – PR) on ray QX.

Step III: Join DR and draw the perpendicular bisector DR.

Step IV: Let it intersect QX at point P. Join PR. PQR is the required triangle.
