A rhombus is simply a quadrilateral with all 4 sides equal. That is all you need to define a rhombus.
A square is a rhombus - but not all rhombuses are squares.
From the simple definition above, it can be easily shown that a rhombus is also a parallelogram - therefore it inherits all the properties of a parallelogram, such as: opposite sides are parallel, opposite angles are equal, diagonals bisect each other.
In addition, the rhombus has the additional properties: the diagonals bisect each other at right angles, and the 2 diagonals cut up the rhombus into 4 congruent right-angled triangles and each diagonal divides the rhombus into 2 congruent isosceles triangles.

This thread will be closed shortly.
After careful consideration, it was decided that user specific threads will no longer be allowed (whether they be one user helping or one user asking for help). We have noticed that the first few threads have spawned multiple others, which is not desirable in the spirit of being an open community. The last thing we want is the Maths forums being full of "User X Maths Help" threads.
You are encouraged to post separate questions in separate threads, though keep in mind a lot of the questions that I have seen so far have been answered before so I suggest to actually do a search first to see if it hasn't been answered already in past threads (which is easier to do when there is a specific thread for a specific question or topic rather than a general user specific thread).
