A square, in its simplest form, is a four-sided polygon with all sides equal in length and all angles measuring 90 degrees. In English, this fundamental shape is referred to as "a square" or "a rectangular quadrilateral." You can say, "The table is a perfect square" or "That room has square walls."
The dimensions of a square are typically described by its side length, which is used to calculate both its area (the amount of space inside) and perimeter (the total length of its boundaries). The formula for the area of a square is side length squared (A = s²), while the perimeter is simply 4 times the side length (P = 4s).
In more technical contexts, you might encounter terms like "square footage" when referring to the area in square units, like square meters or square feet. A "perfect square" refers to a number that is the result of squaring an integer, like 9 (3²) or 16 (4²).
In mathematics, the concept of a square root is essential. The square root of a number squared equals the original number. For example, √16 = 4 because 4² = 16. This idea is fundamental in algebraic equations involving squares.
