Is it:
-Have 2 pairs of congruent opposite sides
-Have 2 pairs of congruent opposite angles
-When a line is drawn from an angle to an opposite angle, the resulting line bisects the two angles (or not)?

Those are all true. (Delete '(or not)' in the last one.)
The diagonals are perpendicular to each other and bisect each other.

The properties of rhombs are:
Each pair of opposite sides are equal and parallel.
Also, each pair of adjacent sides are equal. So, essentially, in a rhombus, all the sides are equal.
The opposite angles are equal. The line drawn from one vertex (NOT angle, that's not the right term to use) to the opposite one is called a diagonal.
The two diagonals are perpendicular bisectors of each other.
The adjacent angles are supplementary. It means that their sum is 180 degrees.
Area of rhombus = (1/2) * (product of diagonals)
The diagonals bisect the angles whose vertices are the diagonal's endpoints.
A diagonal divides a rhombus into 2 congruent triangles
The four triangles formed by the intersection of 2 diagonals are congruent.
These are all the basic propreties of a rhombus. If you want to know more about rhombus than just properties, see this site:

uh, yeah, that's the big three.
opposite sides=
opposite angles=
line drawn through opposite angles bisects both angles---but this is also true of a square
