A quadrilateral is a polygon with four edges (sides) and four vertices (corners). Common types of quadrilaterals include squares, rectangles, trapezoids, and parallelograms, each with distinct properties related to their angles and side lengths. The sum of the interior angles of a quadrilateral is always 360 degrees. Quadrilaterals can be classified as convex or concave based on their angles and shape.
