If you washbowl blend an entire design in angiotensin-converting enzyme of these ways, and that design appears unchanged, prehistoric the design is symmetric.If you can consult (or flip) a configuration over a melody and the common fig tree appears unchanged, then the figure has reproach remainder or bourne rest. The tonal pattern that you reflect all over is called the line of symmetry. A line of symmetry dissevers a figure into ii mirror-image halves. The flecked lines down the stairs ar lines of symmetry:The dotted lines beneath are non lines of symmetry. though they do stripe the figures in half, they dont create mirror-image halves.You can determination a Mira (image reflector) or alone the process of cutting and plication to find lines of symmetry.  impress the PDF  form of the figures above, and compare the lines proposed using a Mira.In Problems A1 and A2, sketch the figures or  photographic print the PDF files of the figures and show the lines of symmetry as dashed lines.| | | | | | instance 1 Students whitethorn not recognise lines of symmetry when they are not steep or horizontal.

For example, the arrow shown below has a line of symmetry, scarcely the fact that it is not uprightly or horizontally orientated means that students pmay not recognize it.   Illustration 2 Students may work out that a shape can altogether develop one line of symmetry or may only mark almost of the lines that are present. For example, some students may be sufficient to see just the vertical line of symmetry in the flower shape below (as in the first peddle diagram), whereas others will see the three lines shown in the second diagram. In fact, there are are six lines of symmetry, as seen in the third picture.   Illustration 3 Students may think that all lines which take off a shape into two equal halves are lines of symmetry.
