No. For example, the two perpendicular sides can be adjacent; in this case, the two sides can be of different length; the lengths of the other two sides aren't unique either.The two perpendicular sides can also be the two opposite sides (i.e., side #1 and side #3, if you count consecutive sides); here, too, there are multiple possible solutions. Just try it out!

What quadrilaterals have parallel sides and perpendicular diagonals?
They are squares and rhombuses
What quadrilaterals sides that are parallel to its opposite side and diagonals that are not perpendicular?
A parallelogram.
What quadrilaterals have all adjacent sides perpendicular?
Rectangles. (Which includes squares.)
Which quadrilaterals have all sides congruent and no sides perpendicular?
A rhombus has all sides congruent with no sides *necessarily* perpendicular. Normally a square is considered a kind of rhombus. So the answer would be "non-square rhombus."
Can you answer which quadrilaterals have their diagonals perpendicular?
The most obvious types of quadrilaterals that have perpendicular diagonals are those with two pairs of adjacent sides the same length - squares, rhombuses, and "kite" shapes.These are all special cases of "orthodiagonal" quadrilaterals. All orthodiagonal quadrilaterals will adhere to the rule that the sum of the squares of the lengths of two opposite (nonadjacent) sides will equal the sum of the squares of the lengths of the other two sides; for successive sides of lengths a, b, c, and d, we have:a2 + c2 = b2 + d2This formula will be true for all orthodiagonal quadrilaterals and any quadrilateral for which this is true will be orthodiagonal (i.e. the diagonals will be perpendicular).
