Fill up the table with help of given example: Quadrilateral Opposite sides All sides equal Opposite angles equal Diagonal equal Diagonals bisect each other equal parallel Parallelogram Yes Yes No Yes No Yes Rectangle

Using the properties of rectangle we have to fill the table as it is done in case of parallelogram. The properties of rectangle are given below: It has four sides and four vertices Each vertex has angle equal to 90 ° The opposite sides are equal and parallel Diagonal are equal and it bisects each other Perimeter is equal to twice of sum of its length and breadth Area is equal to product of its length and breadth It’s a parallelogram with four right angles. Sum of all interior angles equal to 360 ° . Quadrilateral Opposite sides All sides equal Opposite angles equal Diagonal equal Diagonals bisect each other equal parallel Parallelogram Yes Yes No Yes No Yes Rectangle Yes Yes No Yes Yes Yes

Fill up the table with help of given example: Quadrilateral Opposite sides All sides equal Opposite angles equal Diagonal equal Diagonals bisect each other equal parallel Parallelogram Yes Yes No Yes No Yes Square

Using the properties of square we have to fill the table as it is done in case of parallelogram. The most important properties of a square are listed below: All four interior angles are equal to 90 ° All four sides of the square are congruent or equal to each other The opposite sides of the square are parallel to each other The diagonals of the square bisect each other at 90 ° The two diagonals of the square are equal to each other The square has 4 vertices and 4 sides The diagonal of the square divide it into two similar isosceles triangles The length of diagonals is greater than the sides of the square Quadrilateral Opposite sides All sides equal Opposite angles equal Diagonal equal Diagonals bisect each other equal parallel Parallelogram Yes Yes No Yes No Yes Square Yes Yes Yes Yes Yes Yes

Fill up the table with help of given example: Quadrilateral Opposite sides All sides equal Opposite angles equal Diagonal equal Diagonals bisect each other equal parallel Parallelogram Yes Yes No Yes No Yes Rhombus Yes No

Using the properties of Rhombus we have to fill the table as it is done in case of parallelogram. The properties of Rhombus are given below: All sides of the rhombus are equal. The opposite sides of a rhombus are parallel. Opposite angles of a rhombus are equal. In a rhombus, diagonals bisect each other at right angles. Diagonals bisect the angles of a rhombus. Quadrilateral Opposite sides All sides equal Opposite angles equal Diagonal equal Diagonals bisect each other equal parallel Parallelogram Yes Yes No Yes No Yes Rhombus Yes Yes Yes Yes No Yes

Fill up the table with help of given example: Quadrilateral Opposite sides All sides equal Opposite angles equal Diagonals equal Diagonals bisect each other equal parallel Parallelogram Yes Yes No Yes No Yes Trapezium

Using the properties of Trapezium we have to fill the table as it is done in case of parallelogram. The properties of Trapezium are given below: A trapezium has two parallel sides and two non-parallel sides The diagonals of regular trapezium bisect each other The length of the mid-segment is equal to half the sum of the parallel bases, in a trapezium Two pairs of adjacent angles of a trapezium formed between the parallel sides and one of the non-parallel side, add up to 180 ° . Quadrilateral Opposite sides All sides equal Opposite angles equal Diagonals equal Diagonals bisect each other equal parallel Parallelogram Yes Yes No Yes No Yes Trapezium No Yes No No No Yes
