This is called a square or a rhombus. If the vertices of the four corners are all right angles, it is a square. Otherwise it is a rhombus.
Not all polygon have two pairs of parallel sides. For example, a square will, but not a triangle.
An isosceles trapezoid has a pair of parallel sides and a pair of equal base angles
The number of pairs of parallel sides in a polygon varies depending on the type of polygon. For example, a rectangle has two pairs of parallel sides, while a trapezoid has one pair. Regular polygons, like a hexagon, typically do not have any pairs of parallel sides. Therefore, the total can range from zero to multiple pairs, depending on the specific polygon in question.
A rectangle perhaps?
A regular polygon with 100 sides, also known as a hectogon, does not have any parallel sides. In a regular polygon, each side is equal in length, and the angles between adjacent sides are also equal. Since the sides are not aligned in a way that creates parallelism, a regular polygon with any number of sides, including 100, has zero pairs of parallel sides.

It depends on the actual shape of that octagon. It CAN have two pairs of parallel sides. A regular octagon has 4 pairs of parallel sides.

A parallelogram has 2 pairs of parallel sides.

A parallelogram, or variants of polygons with 6 or more sides.
quadrilateral
A regular polygon with 100 sides, also known as a hectogon, does not have any parallel sides. In a regular polygon, each side is equal in length, and the angles between adjacent sides are also equal. Since the sides are not aligned in a way that creates parallelism, a regular polygon with any number of sides, including 100, has zero pairs of parallel sides.
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.
A four sided polygon with two pairs of parallel sides is called a Parallelogram.
An isosceles triangle. It has two pairs of equal sides, which are also not parallel.
