A quadrilateral is a polygon with four sides. There are several types of quadrilaterals including trapezoids which have at least one set of parallel opposite sides, parallelograms where both pairs of opposite sides are parallel, rhombuses which have four equal sides, rectangles defined by having four right angles, and squares that are rectangles with four equal sides and angles.
