From the diagram shown, the quadrilateral ABCD is a rhombus because opposite sides are both parallel and congruent or equal
Properties of a rhombus
The properties of a rhombus include:
- All sides of a rhombus are equal or congruent
- Opposite sides of a rhombus are parallel
- Opposite angles of a rhombus are equal or congruent
- Diagonals bisect each other at right angles
- Diagonals bisect the angles.
- The sum of two adjacent angles is equal to 180 degrees, that is, they are supplementary
From the diagram shown, we can see that line AB is parallel and opposite to line BD and certifies one of the major properties of a rhombus
