At least one pair, or one pair?
If it is one pair, then it depends if the shape is regular or irregular.
A trapezium (has only one pair of unequal parallel lines).
If you mean one pair of parallel lines, then you're talking about a trapezoid.
All triangles have no pairs of parallel lines.Any regular polygon with an oddnumber of sides (regular pentagons, heptagons, nonagons, etc) also have no parallel lines.Most irregular polygons will have no parallel sides, either.
TRAPEZOID
A quadrilateral with one pair of parallel lines would be a trapezoid. : P
A shape with no right angles and one pair of parallel lines would be called a trapezoid in the USA, and a trapezium in Britain.
No, one pair.
trapezoid
Yes, it is possible for a shape to have at least one pair of parallel lines and no lines of symmetry. For example, an irregular trapezoid has one pair of parallel sides but lacks any lines of symmetry due to its uneven angles and side lengths. This demonstrates that parallel lines and symmetry are independent properties in geometric shapes.
A shape with one pair of parallel lines is a trapezoid (or trapezium in some regions). In this quadrilateral, one pair of opposite sides is parallel, while the other pair is not. This characteristic distinguishes trapezoids from other quadrilaterals, such as rectangles and squares, which have two pairs of parallel sides.
A trapezium (has only one pair of unequal parallel lines).
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.
for a shape to be parellel two lines have to never touch if they were extended on forever. a shape with one pair of parellel lines is a trapezoid.

A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.
A shape with only one set of parallel lines is a trapezoid (or trapezium in some regions). In this quadrilateral, one pair of opposite sides are parallel while the other pair is not. This unique characteristic distinguishes it from other quadrilaterals, such as rectangles or squares, which have two sets of parallel sides.
