Playing With Construction                                                                              123

        Now, let us construct this (rectangle) by following the steps given below:

        Step 1:  First of all, we have to draw a side of square AF and it may be of any length. Now we sketch a perpendicular
                 line FE (i.e. AF ⊥ FE).
                 Now put the length for AF into
                 compass and keep the one tip
                 of compass at point F and cut
                 this perpendicular line FE with
                 the help of this compass. Mark                      F                                        E
                 the point E where compass cuts                                                F
                 the line FE which is shown in
                 fig. aside:




                                                                     A                         A


        Step 2:  Now according to above arrangement AF = FE.
                 Similarly, we put the tip of compass of E and cut this extended line FE with the help of this compass
                 at point D. This is also shown in figure below.












                                              F
                                                      E               D






                                               A

        Step 3:  Now draw two perpendicular lines, one is at point D and perpendicular      F                     D
                 to ED and other is at point A and perpendicular to AF. Put the point C
                 where these two perpendicular lines cuts each other and in this way, a
                 rectangle ‘ACDF’ has been constructed.                                    A                      C

        CONSTRUCTION OF SQUARE WITH A HOLE
        Before constructing this, set a rough diagram in your mind. By seeing that       D                         C
        you can approach the process.
        According to this diagram, we observed that ‘E’ is the centre of both circle                         F
        as well as rectangle.
        Now, Let us construct this by following steps given below.                                      E

        Step 1:  First  of  all,  we  have  to  sketch  a  square ABCD  by  using  only
                 compass and pencil.                                                                Centre

                                                                                         A                         B
