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.
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.
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 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 trapezoid has one pair of parallel lines.
