Construct a rhombus ABCD in which AB = 5 cm and diagonal AC = 6.8 cm.

Steps of construction:

1. Draw AB = 5 cm.

2. With A as centre and radius = 6.8 cm, draw an arc.

3. With B as centre and radius = 5 cm, draw another arc, cutting the previous arc at C.

4. Join BC and AC.

5. With A as centre and radius = 5 cm, draw an arc.

6. With C as centre and radius = 5 cm, draw another arc,cutting the previous arc at D.

7. Join CD and DA.

Hence, ABCD is required rhombus.
