### Theory:

A Rhombus may be a flat shape with four equal straight sides. It looks like a diamond.

Properties of rhombus:
• All sides($$S$$) have equal length.
• Opposite sides are parallel, and the opposite angles are equal (it is a parallelogram).
• The altitude is that the space (distance) at right angles to $$2$$ sides.
• The diagonals '$$p$$' and '$$q$$' of a rhombus bisect one another at right angles.
Important!
• The angle between the diagonals of a rhombus is $$90°$$.
• The diagonals of a rhombus need not to be of the same length.
