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.

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 right trapezium.
A trapezoid has one pair of parallel lines.
