Step 1: Draw line segment AB=6cm.
Step 2: Construct ∠BAX=60o.
Step 3: With A as the centre and radius equal to 6 cm , draw an arc
on ray AX.
Step 4: Mark the point of intersection as D.
Step 5: With D as the centre and radius equal to 6 cm, draw an arc.
Step 6: With B as the centre and the same radius, draw another arc such
that it intersects the previous arc at C.
Step 7: Join points C, D and points C, B.
ABCD is the required rhombus.
