A quadrilateral can be classified based on various properties such as the lengths of its sides, the measures of its angles, and the relationships between its sides and angles. Common classifications of quadrilaterals include:

1. Parallelogram: Opposite sides are parallel and equal in length.
2. Rectangle: A parallelogram with all angles equal to 90 degrees.
3. Rhombus: A parallelogram with all sides equal in length.
4. Square: A rectangle with all sides equal in length.
5. Trapezoid: At least one pair of opposite sides is parallel.
6. Kite: Two pairs of adjacent sides are equal in length.
7. Isosceles Trapezoid: A trapezoid where the non-parallel sides are equal in length.
8. Scalene Trapezoid: A trapezoid where no sides are equal in length.

These classifications are based on specific criteria and properties exhibited by the quadrilateral in question.
