neliösuorakulmainen

Neliösuorakulmainen is a Finnish term that translates to "square rectangle" or more commonly, simply "square." In geometry, a square is a special type of quadrilateral, meaning it is a four-sided polygon. It possesses several defining characteristics that distinguish it from other quadrilaterals.

A square has four equal sides, meaning all four line segments forming its boundary are of the same length. Furthermore, all four interior angles of a square are right angles, measuring exactly 90 degrees. This means that adjacent sides of a square are perpendicular to each other.

Due to these properties, a square is both a rectangle (a quadrilateral with four right angles) and a rhombus (a quadrilateral with four equal sides). It is the most regular of all quadrilaterals. The diagonals of a square are equal in length, bisect each other, and are perpendicular.

The area of a square is calculated by squaring the length of one of its sides. If 's' represents the side length, the area (A) is given by the formula A = s². The perimeter of a square is found by multiplying the side length by four, or P = 4s. Squares are fundamental shapes in geometry and appear in various practical applications, from tiling patterns to architectural designs.
