QUADRILATERAL. Four sided closed figures are known as ‘QUADRILATERALS’. There are different types of quadrilaterals. They are differ by their properties like measure of angles, measurements of sides,shapes etc. Different types of quadrilaterals are Square,Rectangle,Parallelogram,Rhombus etc. We can construct a quadrilateral with five measurement.A type of quadrilateral is shown below.

RHOMBUS. Its sides are equal. Its opposite sides are parallel. Its opposite angles are equal. If the sides of a parallelogram are equal then it call as a rhombus. Its diagonals are perpendicular bisector to each other. If the angles of a rhombus are equal (90 degree) then it is call as a square. If the diagonals of a rhombus are equal then it is call as a square. its area is calculated as 1/2d1d2. Rhombus is a type of quadrilateral

RHOMBUS CONSTRUCTION WITH THE HELP OF DIAGONALS. STEP-1 Draw one diagonal horizontally which has 5cm. step-2 Draw a perpendicular to the line.

step-3 measure the half of the second diagonal on either sides of the perpendicular. step – 4 joint the sides.
