                  drawing a Straight Line

                  A straight line can be drawn by moving a pencil along the edge of a

                  scale (ruler).

                  •  Take a ruler and a pencil from your geometry box.

                  •  Place the ruler on a page of your notebook.

                  •  Move the pencil along the edge of the
                       ruler.

                  •  Remove the ruler.                                     0 cm  1  2  3  4  5  6  7  8  9  10  11  12  13  14  15

                                                                           0      1       2       3      4       5      6
                  •  You will get a straight line.
                  Now, you can draw a curved line using a pencil freehand.

                  1.  Try to make some designs using straight and curved lines on dotted paper. Look

                       at the figures drawn here as an example.

                  2.  Count the number of horizontal, vertical and slanting lines in the given figure.
                       Next, draw a figure from your imagination and ask your bench partner to count

                       the different types of lines.

                                                ___ horizontal lines                              ___ horizontal lines

                                                ___ vertical lines                                ___ vertical lines
                                                ___ slanting lines                                ___ slanting lines

                  3.  Name two objects which we can draw using both straight and curved lines.
