a rectangle, which has two sets of parallel side
Not necessarily. A quadrilateral is a plane shape with four straight sides. There is no requirement for a side to be parallel to another.
Any four-sided shape is a Quadrilateral. Square, Rectangle, Parallelogram, rhombus, trapezoid etc. It may have no parallel sides as in a kite, 1 parallel side as in trapezoid or 2 parallel sides as in parallelogram.
A shape with four sides where no side is equal in length is called a trapezoid (or trapezium in some regions). This quadrilateral has at least one pair of parallel sides, while the other two sides can be of different lengths. The sides can vary significantly, leading to a variety of trapezoidal shapes.
Strictly speaking you cannot have one parallel side - you must have one pair. Any irregular polygon with four or more sides can have a pair of parallel sides. Most have no specific names - the only one that does is a trapezium.
a rectangle, which has two sets of parallel side
A rhombus is a four sided shape where all sides are equal length and opposite sides are parallel.
A square has four parallel sides (two pairs of parallel sides).
a rectangle. it has four parallel sides each side is the same length as the one on the other side.
Not necessarily. A quadrilateral is a plane shape with four straight sides. There is no requirement for a side to be parallel to another.
It is not possible to have 1 parallel side since it must be parallel to another side. A four sided shape with 1 PAIR of parallel sides is a trapezium (or trapezoid).
Any four-sided shape is a Quadrilateral. Square, Rectangle, Parallelogram, rhombus, trapezoid etc. It may have no parallel sides as in a kite, 1 parallel side as in trapezoid or 2 parallel sides as in parallelogram.
The shape can only be a rectangle! A rectangle is a four-sided 2-dimentional figure, where every angle is a right angle, opposite sides are parallel, but the 4 sides are NOT equal.
A shape with four sides where no side is equal in length is called a trapezoid (or trapezium in some regions). This quadrilateral has at least one pair of parallel sides, while the other two sides can be of different lengths. The sides can vary significantly, leading to a variety of trapezoidal shapes.
Not sure how you can have only one parallel side. What is it parallel to?
its a shape
No. The sides of a shape don't need to be equal in length to be parallel.
