In a parallelogram, does each diagonal bisect two angles?

Basically, this is a parallelogram: 1. In a parallelogram any two opposite sides are equal.
2. In a parallelogram any two opposite angles are equal.
3. In a parallelogram the diagonals bisect each other.
4. In a parallelogram, each diagonal divides it into two congruent triangles.
5. In a parallelogram, any two adjacent angles have their sum equal to 180„a, that is, they are supplementary.

My favorite parallelogram is a Rhombus:

Each diagonal of a rhombus bisects two angles of the rhombus.

Hence the word Diagonal.......

diagonal:

1541,M.Fr. diagonal, from L. diagonalis, from diagonus "slanting line," from Gk. diagonios "from angle to angle," from dia- "across" + gonia "angle," related to gony "knee" (see knee).
