There is no specific name. For example, if you number the sides of a regular hexagon sequentially from 1 to 6, then sides 1 and 3 are not parallel but there is no specific name for that pair. In the context of the hexagon they do not meet - even if they do so way outside the hexagon.
If they do meet up in the context of the shape, then they will be adjacent or intersecting sides.
A non-regular quadrilateral can have either zero, one, or two pairs of parallel sides. If it has no parallel sides, it is called a trapezoid; if it has one pair of parallel sides, it is still considered a trapezoid; and if it has two pairs of parallel sides, it is classified as a parallelogram. Thus, the maximum number of parallel sides a non-regular quadrilateral can have is two.
It can do. The non-parallel sides of an isosceles trapezium will be equal. Also, one of the non-parallel sides could be equal to one of the parallel sides.
A trapezium has two parallel sides (of unequal length) and two non-parallel sides.
A trapezoid is a shape that has one pair of opposite sides that are parallel. In a trapezoid, the non-parallel sides are called the legs, while the parallel sides are referred to as the bases. This characteristic distinguishes trapezoids from other quadrilaterals, such as rectangles and squares, which have both pairs of opposite sides parallel.
In a trapezium (or trapezoid in American English), the sides are not necessarily the same length. A trapezium is defined by having at least one pair of parallel sides, while the lengths of the non-parallel sides can vary. However, a special type of trapezium, called an isosceles trapezium, has the non-parallel sides of equal length.
They are the lateral sides or the transverse sides.

the Legs
A non-regular quadrilateral can have either zero, one, or two pairs of parallel sides. If it has no parallel sides, it is called a trapezoid; if it has one pair of parallel sides, it is still considered a trapezoid; and if it has two pairs of parallel sides, it is classified as a parallelogram. Thus, the maximum number of parallel sides a non-regular quadrilateral can have is two.
A trapezoid has only one pair of parallel sides. These parallel sides are called the bases of the trapezoid, while the other two sides are non-parallel and are known as the legs of the trapezoid.

Trapezoid
It is a quadrilateral with one pair of parallel sides. The non-parallel sides are typically called the legs, while the parallel sides are known as the bases. Trapeziums are commonly encountered in geometry.
A trapezoid has two parallel sides and two non parallel sides.
