It is a type of [[polygon]] that is a common subject in [[geometry]]. A rectangle has several defining properties, including the fact that opposite sides are equal in length and parallel. This shape is one of the most fundamental in geometry, serving as a building block for more complex shapes and figures.

==Properties and Characteristics==
A rectangle has several key properties:
* All interior angles are equal to 90 degrees (right angles).
* Opposite sides are parallel and equal in length.
* It has two lines of symmetry: one horizontal and one vertical.
* The [[diagonal]]s of a rectangle are equal in length and bisect each other.

===Area and Perimeter===
The [[area]] of a rectangle is calculated by multiplying the length of one side by the length of the adjacent side, often referred to as length × width. The [[perimeter]] of a rectangle is calculated by adding the lengths of all four sides, which simplifies to 2(length + width).

===Special Types of Rectangles===
* '''Square''': A rectangle with all four sides of equal length. It is also a type of [[regular polygon]].
* '''Golden rectangle''': A rectangle whose side lengths are in the golden ratio, approximately 1:1.618.

==Applications==
Rectangles are prevalent in both the natural and built environment, making them significant in various fields such as [[architecture]], [[engineering]], and [[art]]. They serve as the foundational shape for most [[building]]s and structures due to their stability and ease of construction. In [[art]], rectangles are used to create a sense of harmony and balance within a composition.

==Rectangular Coordinates==
In [[cartesian coordinate system|Cartesian coordinates]], a rectangle can be represented by specifying the coordinates of its vertices. This system is fundamental in [[computer graphics]] and [[geometry]] for modeling and calculating properties of rectangular shapes.
