STEP 1: At first draw a base line of 4.3 cm by scale.

STEP 2: Then from point A draw an arc of radius 4 cm and from point B draw an arc of radius 6.8 cm with the help of compass. The intersecting point of both the arcs is D. Join AD and BD.

STEP 3: Now, from point D draw an arc of radius 4.3 cm and from point B draw an arc of radius 4 cm with the help of compass. The intersecting point of both the arcs is C. Join BC and DC.
