Steps of Construction:
Step 1: Draw a line segment BC = 4.5 cm.
Step 2: At the point B, draw ∠XBC = 45°.
Step 3: Draw an arc which intersects XB at point D form point B and with radius 5.6 cm
Step 4: Join DC.
Step 5: Draw a perpendicular bisector of DC which intersects DB at A.
Step 6: Join AC. Hence, △ABC is the required triangle.
