====If a rhombus doesn't have four sides, it is no longer a rhombus. A square also has four congruent angles (90 degrees) and congruent sides, meaning when a rhombus has four right angles, it is also a square. If for example, the sides became two sets of congruent sides opposed to all four being congruent, it would be a kite. Having four congruent sides is the most important.====
