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 shape that has no pairs of opposite sides parallel is a trapezium (or trapezoid, depending on the region). In a trapezium, only one pair of sides may be parallel, while the other two sides are not. Other irregular polygons, such as pentagons or hexagons, can also have no pairs of opposite sides parallel, depending on their specific configurations.
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.
