trapezoids
Geometric shapes that have only one pair of parallel sides include trapezoids (or trapeziums in some regions) and certain types of irregular quadrilaterals. In a trapezoid, the two non-parallel sides are not equal in length and can converge or diverge. These shapes are characterized by their unique angle and side properties, distinguishing them from other quadrilaterals.

Any polygon with four or more sides can have a pair of parallel sides. It is also possible to to have non-polygonal shapes - eg a cigar-shape - that has parallel sides.
The first geometric shape that comes to mind with no perpendicular sides is a triangle.
Any polygon, other than a triangle, can have one pair of parallel sides.

You need at least one pair of parallel sides. Most trapezoids have that.
A shape that has no pairs of parallel lines is called a trapezoid. In a trapezoid, only one pair of opposite sides are parallel, while the other pair is not. This distinguishes a trapezoid from shapes like rectangles, squares, and parallelograms, which have at least one pair of parallel sides. The properties of a trapezoid make it a unique and interesting geometric shape to study.
