No, they do not have that property. The quadrilaterals that have that property are the rhombus (and subsequently, the square) and the kite.
The only property I'm aware of diagonals of a trapezoid having is the fact that they cut each other in the same ratio, which happens to be the ratio between the lengths of the parallel sides.

The diagonals of an isosceles trapezoid are equal in lengths but are not perpendicular to each other at right angles.

No, the only quadrilaterals that I can think of to have perpendicular diagonals are:KiteRhombusSquare (special case of a rhombus)
