# Square vs. Rectangle: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 10, 2023
A square has all sides equal and all angles 90°; a rectangle has opposite sides equal with all angles 90°.

## Key Differences

Square and rectangle, both quadrilaterals, are staples in geometrical studies and daily life applications. A square is a special type of rectangle, characterized by having all its sides equal in length. Simultaneously, a rectangle possesses a distinct trait of having its opposite sides equal, demonstrating a uniform yet flexible aspect in its structure. So, while every square is a rectangle due to its 90° angles, not every rectangle can be a square.

Squares are synonymous with congruency in all aspects, radiating symmetry from every corner and side. Rectangles, while maintaining parallelism and equal length for opposite sides, allow for dissimilarity in the measure between length and breadth. This vital discrepancy between squares and rectangles spawns a myriad of practical applications and architectural considerations, offering a versatile or symmetric choice.

In art and design, squares often symbolize balance and equality due to their equilateral and equiangular nature. Conversely, rectangles offer an elongation or compression aesthetic, providing a distinct, perhaps dynamic or stable visual depending upon orientation. Therefore, the utilization of a square or a rectangle can distinctly influence the aesthetic and balance of a design, impacting perception and interaction.

In mathematical and computational applications, the properties of squares and rectangles serve different purposes. Squares, with their equal sides, often simplify calculations and are straightforward in spatial estimations. In contrast, rectangles cater to diverse problems where varied side lengths are required, enabling a broader application in problem-solving scenarios.

In the world of architecture and urban planning, squares offer a classic, symmetrical, and balanced design, often used in courtyards and plazas. Meanwhile, rectangles provide a utilitarian approach, catering to a variety of spaces like rooms, blocks, or parks, where length may need to dominate over breadth or vice versa. Both the square and rectangle, though similar, offer distinctly different applications and aesthetic impacts, ingrained in our cultural, technological, and natural world.
