                3.  Complete the given pattern and define the rule it follows.









                4.  Draw a circle. Mark points from 1 to 24 at equal distances around it. Join points 1 to

                    11, 11 to 2, 2 to 12 and so on until you reach 1. Three steps are done for you. Complete
                    the pattern.

                    a.















                    b.  A hexagon is drawn on the dotted sheet. Draw
                       at least 6 hexagons to see how it tessellates.











              6.  Here the combination of squares and triangles is used to make a
                    tessellation pattern. Draw the same on grid paper, and then try

                    making  tessellations  using  other shapes  in your notebook.  Can
                    you use a triangle and a pentagon together? If not, give a reason.
