Nope, in order for the diagonals to be perpendicular the shape must be a square (which I guess is a type of rectangle :). The diagonals will cross, but not at a 90degree angle, unless the sides are of equal length.

Not unless the rectangle has 4 equal sides, making it a squre.

no

If the rectangle is square, yes. Otherwise, not.

No but the diagonals of a square intersect at right angles

rectangle

No the diagonals of a rectangle are not perpendicular because they do not cross each other at right angles

No, the diagonals of a rectangle are not perpendicular. The angles between them depend on the dimensions of the rectangle.However, the diagonals of a square are perpendicular (and squares are technically "regular" rectangles, meaning that all sides and angles are equal).
