Shapes with four sides
There are infinite amounts of quadrilaterals that have sides that aren't all equal. In regular quadrilaterals, however there are rectangles and kites that have uneven lengths of sides.
A non-regular quadrilateral is a four-sided polygon that does not have all sides and angles equal. This means that the lengths of its sides and the measures of its angles can vary, resulting in various shapes such as trapezoids, parallelograms, and irregular quadrilaterals. Unlike regular quadrilaterals, such as squares and rhombuses, non-regular quadrilaterals lack uniformity in their dimensions.
Not all irregular quadrilaterals share the same properties; however, they all have four sides and angles that are not equal or do not have equal lengths. Irregular quadrilaterals can have varying side lengths and angles, distinguishing them from regular quadrilaterals like squares or rectangles. Examples include trapezoids and general quadrilaterals that do not conform to specific classifications.
A square is a rectangle in which all side lengths are the same.
Only a square.
There is only one regular quadrilateral, the square. A regular polygon must have equal sides and equal angles, and in the case of quadrilaterals that is a square.
Quadrilaterals are polygons. They can be regular or irregular.
All kites are quadrilaterals, but quadrilaterals are not kites.
All parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms
they have four sides
All 4 sided quadrilaterals are polygons but a square is the only 4 sided regular polygon.
An equilateral parallelopiped, each of whose face is a rhombus.
