Trapezium.
a rectangle is a shape that has two sets of parallel lines a trapezoid only has to have one set of parallel lines
A shape that has all parallel sides, like a square, rectangle, or a rhombus. A trapazoid wouldn't be one because only one set of lines are parallel.
An isosceles trapezoid would seem to fit the given description.

If you mean one pair of parallel lines, then you're talking about a trapezoid.
A trapezium (has only one pair of unequal parallel lines).
Answer: trapezoid Answer: There is no such thing as "one parallel side". Parallel refers to the relationship between TWO lines - so, two lines can either be parallel, or not be parallel. A shape can have one PAIR of parallel sides (e.g. a trapezoid), two PAIRS of parallel sides (e.g., a parallelogram), or more than that (e.g., a regular hexagon has three pairs of parallel sides).

A concave is not a shape. It is a characteristic of one. It is like asking how many parallel lines a small has.
Not sure about angels and parrellel, but a trapezium has four angles and only one pair of parallel lines.
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.
A trapezoid!
