What are the properties of different types of quadrilaterals?
A quadrilateral is any plane figure bounded by four straight lines. Within this definition are special shapes. The Parallelogram : has both pairs of opposite sides parallel (and opposite sides are equal in length). The Rhombus : is a parallelogram with all its sides of equal length. The Rectangle : is a parallelogram with each of its vertex angles equal to 90° (and opposite sides are of equal length). The Square : is a rectangle with all its sides of equal length. The Trapezium : is a quadrilateral with only one pair of parallel sides - which are NOT of equal length. The Isosceles Trapezium : is a trapezium with its two non parallel sides equal in length. The Kite : is a quadrilateral with two pairs of adjacent sides equal in length
