a rectangle,a square,and a parrellelogram
A square is a regular polygon with two sets of parallel sides. A parallelogram is an irregular polygon with one set of parallel sides. A rhombus is an irregular polygon with two sets of parallel sides. A rectangle is an irregular polygon with two sets of parallel sides. *Note - a regular polygon is a shape in which all sides are equal in length and all angles are equal in measurement.
Parallelogram
General term for a polygon with 4 sides is a quadrilateral. A parallelogram is the special case with two pairs of parallel sides.
parallelogram
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.
Since you described it as 2 sets of parallel sides, I'll assume you meant a 4 sided polygon(quadrilateral). This special case is called a rhombus.
You can construct any polygon with more than 4 sides such that two sides are parallel. A quadrilateral in which two lines are parallel is called a trapezoid.
Rectangle
A quadrilateral is a polygon with four 'sides' . A parallelogram is a quadrilateral with two sets of parallel sides.
A HEXAGON. Opposite sides of a regular hexagon are parallel. There being three sets set at different angles.
parallelogram
Any regular polygon with an even number of sides will have opposite sides that are parallel. For quadrilaterals (4-sided shapes), a trapezoid has one set of opposite sides and a parallelogram (rectangle, square, rhombus) has both sets of opposite sides parallel.
