any parallelogram because parallelograms are polygons with four sides.
Two different quadrilaterals have two pairs of parallel sides and have all their angles congruent. They are the square and the rectangle.
A cube has three pairs of parallel faces and all faces are congruent.
Three pairs.
A quadrilateral or a pentagon can have up to 2 pairs of parallel sides.A hexagon or heptagon can have up to 3 pairs of parallel sides.and so on.So, apart from a triangle, any polygon can have two sets of parallel sides.
That's a rhombus.
A parallelogram.
It's possible for any polygon with an even number of sides to have 2 pairs of congruent and parallel sides.Every parallelogram, including all rhombera, rectangles, and squares, must have.
Rhombus (or square).
A four-sided polygon with congruent sides and angles, and two pairs of parallel sides.
It could be an irregular polygon with 6 or more sides or, if a quadrilateral, it could be a parallelogram.
A polygon.
A quadrilateral with congruent pairs of adjacent sides and no parallel sides is a kite.
A cube has three pairs of parallel faces and all faces are congruent.
A kite is a four-sided polygon with two pairs of congruent adjacent sides.
Not all polygon have two pairs of parallel sides. For example, a square will, but not a triangle.
There are 56 pairs of congruent angles.
