菱形 Rhombus

(重定向自Rhombi)

菱形是四边相等的四边形,由菱叶片的形状而得名。菱形属于特殊的鹞形、平行四边形,除了这些图形的性质之外,它还具有以下性质:

  • 对角线互相垂直平分
  • 边四边相等。

正方形是四个角都垂直的菱形。

菱形面积为对角线相乘除以二(鹞形面积): A = \frac{1}{2} \cdot x \cdot y
或边长的平方乘以其中一只角的正弦(平行四边形面积): A = a^2 \cdot \sin \alpha

菱形周界为边长的四倍 : U = 4 \cdot a

内切圆半径:

 r = \frac{1}{2} \cdot a \cdot \sin \alpha

Rhombus 菱形

(重定向自Rhombi)
The rhombus has a square as a special case, and is a special case of a kite and parallelogram.
A rhombus. Each angle marked with a black dot is a right angle. The height h is the perpendicular distance between any two non-adjacent sides, which equals the diameter of the circle inscribed. The diagonals of lengths p and q are the red dotted line segments.

In Euclidean geometry, a rhombus(◊), plural rhombi or rhombuses, is a simple (non-self-intersecting) quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond, after the diamonds suit in playing cards which resembles the projection of an octahedral diamond, or a lozenge, though the former sometimes refers specifically to a rhombus with a 60° angle (see Polyiamond), and the latter sometimes refers specifically to a rhombus with a 45° angle.
