  1. The rhombus is a parallelogram, so its opposite sides are equal and parallel in pairs. Opposite corners of a rhombus are equal, and adjacent corners complement each other up to 180 °.
  2. The diagonals of the rhombus intersect at right angles and are halved at the intersection. Thus, the diagonals divide the rhombus into four right-angled triangles.
  3. The diagonals of a rhombus are the bisectors of its corners.
  4. The sum of the squares of the diagonals equals the square of the side times 4.
  5. The midpoints of the four sides of the diamond are the vertices of the rectangle.
  6. The diagonals of a rhombus are perpendicular to the axes of its symmetry.
  7. Any rhombus can contain a circle whose center lies at the intersection of its diagonals.

A square is a special case of a rhombus. Sometimes a square is defined as a rhombus in which all angles are equal.
