a rectangle
A quadrilateral with congruent pairs of adjacent sides and no parallel sides is a kite.
A kite is a quadrilateral with two pairs of adjacent congruent sides. The angles between the unequal sides are equal.
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.

A rectangle has two pairs of congruent sides, but any pair of adjacent sides is non-congruent.
- Opposite angles are two angles that don't share a side. A quadrilateral has two pairs of them. - Adjacent angles are angles that share one side. A quadrilateral has four pairs of them.
It can also be a kite. That has two congruent pairs of sides but unlike a parallelogram they are adjacent, not opposite. A parallelogram with congruent diagonals is a rectangle.
