The picture you are looking for is a parallelogram.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
There is no particular name. It need not be a regular polygon - for example, consider a stretched hexagon.
A quadrilateral
A regular polygon with an even number of sides.
Dragon is the answer
A quadrilateral
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.
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
Trapezoid. It has two parallel lines on opposite sides.
parallogram or quadrilateril
B. False
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.
A square.
