Quadrilaterals - Geometry

This geometry video tutorial provides a basic introduction into the different types of special quadrilaterals and the properties of quadrilaterals. It contains plenty of examples and practice problems of calculating the area, perimeter and diagonal length of many quadrilaterals such as squares, rectangles, rhombuses, kites, trapezoids, and parallelograms as well as missing sides and missing angles.
