A quadrilateral is a polygon with four sides. A parallelogram is a quadrilateral in which the opposite sides are parallel.
The parallel sides of a polygon are sides that are segments of parallel lines. A polygon need not have any parallel lines. A triangle, for example, is a polygon that cannot have parallel lines.
A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.
Yes, it has sides that are straight line segments. Exactly one pair of opposite sides is parallel. Polygons do not have curved sides.
Every 4-sided polygon in which the opposite sides are parallel is a parallelogram. Opposite sides are equal too, but it's not necessary to make that an explicit requirement, because if both pairs of opposite sides are parallel, then they also wind up being equal.
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.
NO!!!! A parallelogram is a polygon of four sides. The opposite sides are parallel and equal in length.
A quadrilateral
A square.
a trapezoid
Any even sided irregular polygon can have opposite sides parallel. A parallelogram would be the simplest of these.
B. False
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.
Trapezoid. It has two parallel lines on opposite sides.
