Construct a rhombus ABCD in which AB = 4.3 cm and ∠A = 45°.

Steps of construction :

1. Draw AB = 4.3 cm.

2. Construct ∠BAX = 45°.

3. On AX, cut off AD = 4.3 cm.

4. With B as centre and radius = 4.3 cm, draw an arc.

5. With D as centre and radius = 4.3 cm, draw another arc, cutting the previous arc at C.

6. Join CB and CD.

Hence, ABCD is the required rhombus.
