What is the mathematical diamond formula?
Half of the diagonal product is equal to the area of the diamond.

The area formula of diamond:

1 rhombus area formula is derived from triangle area formula. Diamond area = sum of the areas of two triangles

2. Half of the diagonal product, that is, S=(a×b)÷2 (any quadrilateral with diagonal lines perpendicular to each other can be used).

3.s diamond = base * height (like parallelogram area formula, diamond is a special parallelogram).

4. Let the side length of the diamond be a and the included angle be x, then the area formula is: A side length.

α-included angle

D- long diagonal length

D- short diagonal length

S=Dd/2

=a2sinα
