Two fantastic Geogebra applets have been included in the 'shape properties of quadrilaterals' resources on www.MathsMaster.Org. The first is a great activity where you have to drag the vertices of a quadrilateral to make different shapes, watching the angles and the side lengths change in real time. The second looks at the rotational symmetry properties of quadrilaterals.

Enjoy!

You provide very good explanation about quadrilaterals and I am here to discuss the definition and properties of quadrilaterals as they are figures with four sides and four angles. There are many different types of quadrilaterals, which are classified by their sides and angles here are some examples-rectangle, parallelogram, trapezoid, rhombus, square and kite.
