                                            Drawing Straight Lines

        We  have  already  learnt  how  to  trace  a  shape  using  bottoms  of  the

        solids. Here, we use straight-edged object like ruler to draw a straight
        line.

        A 15-centimetre scale is available in our geometry box.

        We can use it to draw a line of the given length below 15 cm.

        Draw a line of length 5 cm.

        Step 1: Keep your scale on a sheet of paper.

        Step 2: Make a dot (say, A) with the mark of 0 on the scale using a
                    pencil. Also, mark another dot (say, B) on 5.
