That's a trapezoid.
trapezoid
If two sides are parallel and the other two aren't, the shape is a trapezoid.
For a shape to have parallel sides it needs at least 4 sides
A trapezium is a shape with four sides. Of these, one pair of sides are parallel. The only restriction on the other pair is that they are not parallel (because you then have a parallelogram).
A trapezoid. Two sides are parallel, the other two are not.
A 25-sided shape would have no parallel sides !
A rectangle is a shape that has four sides with two parallel lines.
If it has four equal sides, then two parallel sides implies two PAIRS of parallel sides. The shape is a rhombus.
A quadrilateral is a shape with four sides. A parallelogram is a quadrilateral that has two pairs of parallel sides (i.e. the sides opposite each other are parallel). A rectangle, for example, is a parallelogram. A trapezoid, however, is an example of a quadrilateral that is not a parallelogram - it has four sides, but only two of them are parallel to each other.
Any polygon with four or more sides can have parallel sides.
A four sided shape with 2 parallel sides is called a trapezium. A four sided shape with 2 pairs of parallel sides is called a Parallelogram; This includes squares, rectangles and rhombi. If you want to find more about this you can check on google.
None. A parallel is not a shape and so does not have any sides.
