Three easy to use online calculators to calculate the area, perimeter, diagonals and angles of a rhombus. The first calculator may be used if you know the side and angle of a rhombus and need to find the other characteristics. The second calculator may be used if you know the two diagonals and the third calculator may be used if you know the area and perimeter.

1 - You know the side and one angle of a rhombus.

How to use the calculators

Enter the side and one angle (in degrees) as positive real numbers and press "enter". The outputs are: the area, perimeter, the two diagonals, the second angle and the perpendicular distance between two parallel sides of the rhombus.

2 - You know the two diagonals of a rhombus.

How to use the calculators

Enter the two diagonals as positive real numbers and press "enter". The outputs are: the area, perimeter, side, the two angles and the perpendicular distance between two parallel sides of the rhombus.

3 - You know the area and the perimeter of a rhombus.

How to use the calculators

Enter the area and the perimeter as positive real numbers and press "enter". The outputs are: the side, the two diagonals, the two angles and the perpendicular distance between two parallel sides of the rhombus.
