A quadrilateral
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
This is called a Parallelogram. Each pair of opposite sides will then be the same length. If all four sides are the same length, and opposite sides are parallel, then it is a rhombus. NB: If all four sides are the same length then the opposite sides must be parallel.
In parallelogram each two opposite sides are parallel and equal in length
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
A regular polygon with an even number of sides.
A square.
A regular polygon with an even number of sides.
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.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
Any polygon with an even number of sides can have opposite sides that are congruent and parallel.

Any even sided irregular polygon can have opposite sides parallel. A parallelogram would be the simplest of these.
parallogram or quadrilateril
B. False
In parallelogram each two opposite sides are parallel and equal in length
