- All sides are equal.
- Alternate angles are equal.
- Its centre is equidistant from its sides, hence it has an incircle.
- Its axes of symmetry bisect opposite angles.
- Diagonals intersect at equal angles.
- The perimeter of rhombus = 4a (*a is the side length)
- The area of rhombus = h x s = s2 sin(A) = s2 sin(B) = (p × q)/2 (*s is a side lenght of rhombus, h is a height of rhombus, p is a long diagonal of rhombus, q is a short diagonal of rhombus)
