A diamond is actually an informal term for a rhombus, which has four equal sides(congruent is not used to refer to equal sides), with the opposite sides being parallel to one another.So a "diamond" has four equal sides and two pairs of parallel sides.
A polygon with 2n sides (n>1) can have opposite sides congruent.
A square's opposite sides are parallel and all the sides are congruent.
Yes. A parallelogram has congruent opposite sides as well as congruent opposite angles.
A rhombus.
Diamond
Parallelogram, Rectangle, and Isosceles Trapezoid, opposite sides are congruent.
A kite
This quadrilateral is a trapezoid. In a trapezoid, one pair of opposite sides is parallel, and one pair of opposite sides is congruent. The other two sides are not parallel or congruent.

A parallelogram has two pairs of congruent sides, and the opposite sides are congruent.
A polygon with 2n sides (n>1) can have opposite sides congruent.
The Opposite Sides Parallel and Congruent Theorem states that if a quadrilateral has a pair of opposite sides that are parallel and congruent, then the quadrilateral is a parallelogram.
A square's opposite sides are parallel and all the sides are congruent.
A rectangle is a quadrilateral with four sides. All angles are right angles, the diagonals are congruent, and the opposite sides are all equal. A rhombus (diamond) is a quadrilateral with congruent daigonals and equal angles.
