parallogram or quadrilateril
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.
A four-sided polygon with two parallel sides is called a trapezoid (US) or trapezium (UK). It requires that the parallel sides are not equal in length, or they would form a parallelogram. A trapezoid's bases are parallel, but the legs are not.trapezoid
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
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.
Any even-sided, regular shape will have opposite sides parallel. A square, hexagon, octagon and decagon are just four examples !
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
A four-sided polygon with opposite sides parallel could be a square, a rectangle, or a rhombus.If it has one pair of opposite, parallel sides, then it is a trapezoid. If it has two pairs of opposite, parallel sides, then it is a parallelogram.
Any even sided irregular polygon can have opposite sides parallel. A parallelogram would be the simplest of these.
A pallelogram or rhombus
A rhombus or a parallelogram
None. (As there are an odd number of sides, each side is opposite a vertex and there are no parallel sides.)
A square or a rhombus
A trapezoid is a four-sided polygon (quadrilateral) that is not a parallelogram. In a trapezoid, at least one pair of opposite sides is parallel, while the other pair is not. This distinguishes it from parallelograms, where both pairs of opposite sides are parallel. An example of a trapezoid is a rectangle, which has one pair of opposite sides that are parallel and the other pair that is perpendicular to them.
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.
A square is a four-sided polygon with two congruent parallel sides.
A square or a rectangle
A four-sided shape is a quadrilateral. With only one pair of parallel sides, it would be called a trapezoid (UK trapezium).
