                3.  draw the line(s) of symmetry of the following figures. How many line(s) of symmetry
                    these figures have?
                    (a)                     (b)                      (c)                      (d)






                    (e)                      (f)                     (g)                      (h)





                4.  Complete the following figures by considering the dotted line as a line of symmetry.
                    (a)                              (b)                             (c)










                5.  Write the capital letters of english alphabet which have:

                    (a)  horizontal line of symmetry only.

                    (b)  vertical line of symmetry only.
                    (c)  both horizontal and vertical lines of symmetry.


              SlideS, fliPS And turnS

              A shape or figure can be moved in various ways. These are: sliding, flipping and turning.
              Slide

                                                                                                         Note
              When  a  shape  simply moves from one place  to
              another in one direction, it slides.                                                  When you slide an
                                                                                                    object, you move
              Here, an arrow slides towards the right.                                              the object across.

              flip

              When  a shape  is turned over a straight line to  form a mirror
              image, we called it flipped. A shape can flip either horizontally
              or vertically.
              turn                                                                        Horizontal flip    Vertical flip

              When a shape is rotated clockwise or anti-clockwise through an angle, it turns. A turn can

                                                                                                              
                                              
                                                                         
              be a quarter turn        1  or 90° , a half turn     1  or 180°  a three-quarter turn   3  or 270°  and a
                                              
                                                                                                              
                                                                                                    
                                                                         
              full turn (360°).       4                       2                                  4       
              teacher’s    Discuss with the children that slide (translation), flip (reflection) and turn (rotation) are different forms of
                   tip     transformation we can do to a shape. After any of these transformations, the size, area and length of the shape
                           remain the same.
