Parallelogram opposite sides are congruent opposite sides parallel
Parallelogram, Rectangle, and Isosceles Trapezoid, opposite sides are congruent.
always
Any polygon with 2n sides (n integer) where opposite sides are parallel, will have its opposite angles congruent.
If two opposite sides are congruent in length and direction then they are parallel sides. THat would mean the other two sides are congruent making 4 parallel sides or a parallelogram
rectangle
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.
