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
