We want to state whether one pair of opposite sides in a kite is always, sometimes, or neverparallel. Let's begin by recalling the definition of a kite.
Definition of a Kite
A kite is a quadrilateral with exactly two pairs of consecutive congruent sides. Unlike a parallelogram, the opposite sides of a kite are not congruent or parallel.
This means that one pair of opposite sides are never parallel in a kite.

Parallel Opposite Sides
We know that the opposite sides are never parallel in a kite. Now we can find a figure that has one pair of parallel opposite sides. Let's consider the definition of a trapezoid.
Definition of a Trapezoid
A trapezoid is a quadrilateral with exactly one pair of parallel sides.
By the definition of a trapezoid, we can conclude that a figure that has one pair of parallel opposite sides is a trapezoid.
