### Characterizations of Rhombus

- Parallelogram with all sides congruent
- Diagonals perpendicular
- Each diagonal bisects a pair of opposite angles
- 2 pair of parallel sides
- Opposite sides are congruent
- Opposite angles are congruent
- Consecutive angles are supplementary
- Diagonals bisect each other
- Diagonals are congruent

## Calculate Area, Perimeter of Rhombus

### Formula:

(i). A = b × a

(ii). A = ½ × d_{1} × d_{2}

(iii). A = s^{2} × sin(a)

(iv). Perimeter = 4S

A - the area of a rhombus

a - is the altitude (height)

b - is the length of the base

d

_{1}, d

_{2}- the length of diagonals

s - length of any side
