Diamond is a figure often mentioned in mathematical geometry, so do you know the relevant knowledge points of diamond? The following is the "What is the rhombic area formula and perimeter formula" compiled by me for your reference only. Welcome to read this article.

The area of the rhombus Let the area of the rhombus be S, the side length be A, the height be B, the two diagonal lines be C and D respectively, and the minimum internal angle be ∠ θ, then there are:

1, S=ab (the area of rhombic parallelogram is equal to the base multiplied by the height);

2.S=cd÷2 (the area of a quadrangle with rhombus and other diagonals perpendicular to each other is equal to half of the product of two diagonals);

3. s = a 2 symplectic θ.

The formula of diamond circumference is:

C=4a (where c is the perimeter and a is the side length of the diamond).

On the same plane, a group of parallelograms with equal adjacent sides are rhombic, and quadrilaterals with equal four sides are rhombic.

Further reading: the essence of diamonds

1, the diamond has all the properties of a parallelogram;

2. All four sides of the diamond are equal;

3. The diagonals of the rhombus are equally divided vertically with each other and equally with each group of diagonals;

4. The diamond is an axisymmetric figure with two symmetrical axes, that is, the straight lines where the two diagonals are located;

5. A diamond is a figure with a symmetrical center.
