Parallelogram
A parallelogram
This is a parallelogram. The first requirement is 2 pairs of congruent sides where the congruent sides are not adjacent. This is like a rectangle (excluding a square) that has two pairs of congruent sides where the congruent sides are not adjacent. But the angles are not all congruent (as set in the question) which pushes the shape into the "next less regular" shape, the parallelogram. The angles will not all be congruent, but it will have 2 pairs of congruent angles. There is no way to avoid the 2 pairs of congruent angles because of the requirement that the shape must have 2 pairs of congruent sides (the first requirement).
A parallelogram has two pairs of congruent sides.
a kite (two pairs of adjacent congruent sides) or a trapezoid (one pair of parallel sides).
A quadrilateral with congruent pairs of adjacent sides and no parallel sides is a kite.
In geometry, a kite, or deltoid is a quadrilateral with two disjoint pairs of congruent adjacent sides, in contrast to a parallelogram, where the congruent sides are opposite.
A kite is similar to a parallelogram in that both have opposite pairs of congruent sides. However, unlike a parallelogram, a kite does not have congruent opposite angles. Additionally, a kite has two pairs of adjacent sides that are congruent, while a parallelogram has all sides congruent.
A parallelogram has two pairs of congruent sides, and the opposite sides are congruent.
A parallelogram has two pairs of congruent sides.
