Someone never had to deal with mathematical proofs, only layman's definitions.

All properties of a parallelogram apply:

Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent
Consecutive angles are supplementary
Diagonals bisect each other

AND

All angles are congruent
All sides are congruent
Diagonals are congruent
Diagonals are perpendicular
Diagonals bisect opposite angles
