Construct a triangle PQR with QR=7cm ,angle Q=75 degrees and PQ-PR=3cm

 

 

 

 

STEP I: Draw a line QR of length 7 cm and contruct angle XQR=75°

STEP II:Cut a line segment QM=3 cm(PQ-PR)

STEP III: Join M and R and draw the Perpendicular Bisector of MR and the point at which it cuts QX will be P.

STEPIV: join P and R and the triangle PQR is Constructed.
