A parallelogram has two sets of congruent parallel sides.
If only two sides of one figure are congruent to two sides of another figure, you can say nothing about the opposite angles.

A parallelogram has two pairs of congruent sides, and the opposite sides are congruent.
It is a Rhombus.
Opposite sides are parallel, Consecutive angles are supplementary, Opposite angles are congruent, Opposite sides are congruent (APEX)
A parallelogram is a quadrilateral (four-sided figure) in which both pairs of opposite sides are parallel. You can check for that, specifically. As an alternative, you can check for any of the following conditions: * Opposite angles are congruent * Opposite sides are congruent
A polygon with 2n sides (n>1) can have opposite sides congruent.
The shape described is a rhombus. A rhombus has four sides that are all congruent, and its opposite sides are parallel. Additionally, while opposite angles are equal, none of the angles are right angles. This geometric figure maintains these properties, distinguishing it from other quadrilaterals like rectangles or squares.
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 parallelogram, and any polygon with 180 degree rotational symmetry.
It is a rectangle or a square.
