area = (e*f)/2
perimeter = a*4
a = square root of (e/2)^2+(f/2)^2
Arcs are simply calculated by decomposing the rhomb into for rect-angled triangles.
What is a rhomb?A rhomb is a quadrangle having four sides of the same length. Therefore, opposing sides have to be parallel and opposing angles have to be equal. A rhomb is at the same time a rhomboid and a kite.
How to do rhomb calculations?The simplest calculations can be done if you know the lengths of the diagonals. The rhomb is uniquely determined by them.
The side length of a rhomb equals square root of ((e/2)²+(f/2)²), als can be seen by Pythagoras.
The area equals e*f/2.
If you want to solve some examples, just enter them above.
