Sol:
Steps of construction:
Step 1: Draw a line segment BC of 6cm.
Step 2: At B draw an angle XBC of 90o.
Step 3: with center B and radius 10cm draw an arc which intersects XB at D.
Step 4: Join DC.
Step 5: Draw the perpendicular bisector of DC which intersects DB at A
Step 6: Join AC
Therefore ΔABC is the required triangle
