                    Lesson 1

 

                                                           Problem:                   Does the figure have a line of symmetry?          

                                                                                                                                html.png

 

                                                            Solution                    A line of symmetry is any line that can be drawn

Step 1:                        through a figure which divides it into equal parts.   

                                                           

                                                            Solution                    Above figure has 2 lines of symmetry as we get equal parts through them 

Step 2:                            

 

                                                            Solution                    The answer is:

Step 3:
