Construct a triangle PQR in which QR = 6cm, ∠Q = 60° and PR – PQ = 2cm.
Answer
Steps of Construction:
Step 1: A ray QX is drawn and cut off a line segment QR = 6 cm from it.
Step 2:. A ray QY is constructed making an angle of 60º with QR and YQ is produced to form a line YQY'
Step 3: Cut off a line segment QS = 2cm from QY'. RS is joined.
Step 5: Draw perpendicular bisector of RS intersecting QY at a point P. PR is joined.
Thus, ΔPQR is the required triangle.
