A polygon with 4 sides is a quadrilateral.
A shape with three or more sides is a polygon. Not sure there is a special name for 4 or more sides.
It is a general polygon. Unlike with triangles, there is no special name for such a shape.
Yes because all quadrilaterals have 4 sides
a quadrilateral wow
General term for a polygon with 4 sides is a quadrilateral. A parallelogram is the special case with two pairs of parallel sides.
The only terms that definitely apply are "quadrilateral" (or more specifically an "incongruent quadrilateral") and "quadrangle."The polygon may also be a trapezoid or a trapezium, but it is also possible to have a trapezoid or trapezium with two sides equal. Also note that the British and American definitions of trapezoid and trapezium are exactly reversed: an American trapezoid is a British trapezium, and a British trapezoid is an American trapezium.A polygon with 4 sides is called a quadrilateral. There is no special name to indicate that it has no two equal sides.
