Rhombus

The difinition of rhombus :
- A quadirateral with four equal sides.
- Rhombus can be formed by combining two congruence isosceles triangles through its bases.
- If both diagonals of a quadrilateral are perpendicular and bisect each other.

The properties of rhombus :
1. Have 4 sides. All sides are equal
2. Opposite angle of rhombus are equal.
3. The diagonal divide it to be two part with same length and upright
4. Both diagonals are perpendicular. This means the intersection of the diagonals of a rhombus form 90 (right angle).
5. The sum of two adjacent angles is 180. Adjacent sides (ones next to each other) of a rhombus are supplementary. This means that their measures add up 180.
