The diagonals of any parallelogram (square, rhombus, rectangle, rhomboid) bisect each other. The difference is the the diagonals are equal in length for a square and rectangle, and not equal for a rhombus or rhomboid (oblique diamond).
True
may or may not be
If you are talking about the diagonals of a quadrilateral, the only quadrilateral that have diagonals that are perpendicular and bisect each other is a square, because a rectangle has bisecting diagonals, while a rhombus has perpendicular diagonals. And a square fits in both of these categories.
diagonals.
the anser to this question is a trapiezuim as it could have right angles and its diagonals definatly do not bisect each other

The missing word is "bisect".
A quadrilateral is a parallelogram if and only if its diagonals bisect each other (this should be in any geometry book)
