A quadrilateral is a polygon that has four edges (sides) and four vertices (corners). Quadrilaterals can be classified into various types based on their side lengths and angles, such as squares, rectangles, and trapezoids. Understanding the properties and relationships of quadrilaterals is crucial in both geometry and real-world applications, as they form the basis for more complex shapes and structures.
