A kite or arrowhead.
You divide the length of one adjacent side by the length of the other adjacent side.

The quadrilateral you are describing is a scalene trapezoid. It has two sides of unequal lengths (the long sides) and two other sides of equal, shorter lengths (the short sides). This shape does not exhibit reflective symmetry and lacks right angles, fitting your criteria perfectly.
The diagonals of rectangles are rotational lines of symmetry but not reflective. To be reflective lines, folding along the line has to give the same shape on each side.
Knowing the length of the hypotenuse doesn't tell you the length of either adjacent side. You also need to know at least one other piece of information, like the other side, or an angle.
There are very many attributes. Some of these are:It is a two-dimensional shape. It has four sides. The sides are of equal length. It has two pairs of parallel sides. It has four vertices. Each vertex is a right angle. It has two diagonals. The diagonals bisect each other. The diagonals meet at right angles. It has rotational symmetry of order four. It has four axes of reflective symmetry. If the sides are of rational length then the diagonals are of irrational length (and conversely).
That is a parallelogram.

The number 11 has 0 lines of symmetry. A line of symmetry is a line that divides an object into two equal halves that are mirror images of each other. Since the number 11 is a single digit number with no reflective symmetry, it does not have any lines of symmetry.
