It has two 5-tuples and 5 pairs of parallel lines. It need not have any line of symmetry.
No but it does have an horizontal line of symmetry
No but it does have parallel line segments of different lengths and 1 line of symmetry
Trapezoid
A rectangle has two lines of symmetry, the lines that connect the midpoints of the parallel sides of a rectangle are lines of symmetry of the rectangle.
You cannot have one parallel line. There must be another line that it is parallel to. Also, 1 symmetry is meaningless - you can have one axis of symmetry or rotational symmetry of order one. The answer will depend on which one it is.

No but it does have an horizontal line of symmetry
An isosceles trapezoid has 1 vertical line of symmetry
Yes. Think of a kite shape. Symmetry along its length but no parallel sides.
A line which divides a body into two parts, such that each part is the mirror image of the others, then the line is called a line of symmetry. If such a line is parallel to the horizontal plane, then it is called a horizontal line of symmetry. Else, if the line of symmetry is perpendicular to the horizontal plane then it is a vertical line of symmetry.

A rectangle has two lines of symmetry, the lines that connect the midpoints of the parallel sides of a rectangle are lines of symmetry of the rectangle.
The diagonals of a rectangle aren't lines of symmetry unless it's square.
It has one line of symmetry across the horizontal 'bar' of the H, and one vertical line parallel to the 'uprights' - mid-way along the horizontal bar.
z does not have a line of symmetry. z does not have a line of symmetry. z does not have a line of symmetry. z does not have a line of symmetry.
