quadriláteros

Quadrilaterals are four-sided polygons, which means they have four vertices and four edges. They are a fundamental concept in geometry and can be classified into various types based on their properties, such as the lengths of their sides and the measures of their angles. The sum of the interior angles of any quadrilateral is always 360 degrees. Quadrilaterals can be further categorized into specific types, including:

- Parallelograms: Quadrilaterals with two pairs of parallel sides. Examples include rectangles, rhombuses, and squares.

- Trapezoids (or Trapeziums): Quadrilaterals with at least one pair of parallel sides. They can be isosceles (with non-parallel sides of equal length) or scalene (with no sides of equal length).

- Kites: Quadrilaterals with two pairs of adjacent sides that are equal in length.

- Cyclic Quadrilaterals: Quadrilaterals that can be inscribed in a circle, meaning all four vertices lie on the circumference of a single circle.

Quadrilaterals are studied in various mathematical contexts, including Euclidean geometry, coordinate geometry, and trigonometry. They are also used in practical applications, such as architecture, engineering, and computer graphics, where understanding their properties is essential for design and analysis.
