It could be a cylinder or a cuboid
A four-sided polygon with two parallel sides is called a trapezoid (US) or trapezium (UK). It requires that the parallel sides are not equal in length, or they would form a parallelogram. A trapezoid's bases are parallel, but the legs are not.trapezoid
Prism
Not all polygon have two pairs of parallel sides. For example, a square will, but not a triangle.
A square is a four-sided polygon with two congruent parallel sides.
A prism has two congruent parallel bases.
There are several cases: any 3 dimensional or more object. Since a polygon is defined as being confined to a single plane, any shape that violates the plane is not a polygon but may still have parallel bases. For cases in only 2 dimensions: Any object that has curves in addition to the parallel bases. A polygon's definition includes only straight sides. Finally, unclosed shapes can have 2 parallel bases with out being polygons even if in a single plane and made up of only straight line sides. A polygon must be closed.
A right trapezoid is a four-sided polygon with two right angles and two parallel sides.
A square is a regular polygon with two sets of parallel sides. A parallelogram is an irregular polygon with one set of parallel sides. A rhombus is an irregular polygon with two sets of parallel sides. A rectangle is an irregular polygon with two sets of parallel sides. *Note - a regular polygon is a shape in which all sides are equal in length and all angles are equal in measurement.
Any polygon with more than 3 sides can have two pairs of parallel sides.If it has only four sides and they make two parallel pairs, then it's a parallelogram.
You can construct any polygon with more than 4 sides such that two sides are parallel. A quadrilateral in which two lines are parallel is called a trapezoid.
