If we make a parallelogram with adjacent sides 6 cm and 6 cm and a diagonal of 8 cm, we will get
Rhombus
Since, all the sides of the parallelogram are equal, it will be a rhombus or a square. But, the angle included between the sides cannot be 90 degrees as 62 + 62 ¹ 82.
Thus, the parallelogram is a rhombus.
