Pls answer this question sir..

Dear student,

We know diagonals of rectangle bisect each other .So
Step 1-  Draw a line As : AO  = $\frac{6}{2}$   = 3 cm 

Step 2  - Now draw a angle of 45$°$ at point O , and cut arc of 3 cm and mark that point is B , So we have  $\angle$ AOB  = 45$°$  .



Step 3 - Now we extend our line segment AO to AC as take arc of OC  = 3 cm , and OB to BD , as OD  = 3 cm



Step 4 - Now join Point A , B , C  and  D  
Hence we obtain ABCD  as a rectangle  .
