A quadrilateral with two parallel sides is a trapezoid.
A square and a rhombus
If the shape (a quadrilateral) has only 2 parallel sides, it is a trapezoid (UK trapezium).A shape with four sides and two sets of parallel sides is a parallelogram (rectangle, square, rhomboid, rhombus) because these figures have four sides and two sets of parallel sides.
A parallelogram is flat, with four straight sides, with opposite sides being parallel.
A square (i am pretty sure) has 2 sets of parallel sides and four parallel sides.
The name of the four-sided shape that has only one pair of parallel sides is known as a trapezoid. The other two sides are not parallel to each other. There are many other shapes with more than four sides that have one pair of parallel sides but these typically don't have special names. So assuming the question is only referring to four-sided figures, the answer is a trapezoid.
Atrapezoidhas four sides and only two of the four sides are parallel. A square,parallelogram, and kite have four sides and have multiple pairs of parallel sides.
A square has four parallel sides (two pairs of parallel sides).
A regular octagon has four pairs of parallel sides.
A rectangle is a shape that has four sides with two parallel lines.
It has two pairs of parallel sides.
Any polygon with four or more sides can have parallel sides.
2-dimensional figures. Four straight sides. Four angles that add to 360 degrees. Parallel opposite sides. Equal opposite sides. Equal opposite angles. Bisecting diagonals.
