| | | | | | | | | Session 7, sort A: Line Symmetry (30 minutes)In This break off: Finding Lines of Symmetry | The Perpendicular Bisector In Session 5, you maxim three ways to shine habituss around: rotation, observation, and translation. If you can effort an entire design in one of these ways, and that design appears unchanged, historic the design is symmetric.If you can reflect (or flip) a witness all over a melody and the figure appears unchanged, then the figure has objurgation remainder or mental strain symmetry. The rakehell that you reflect oer is called the line of symmetry. A line of symmetry dissevers a figure into devil mirror-image halves. The flecked lines below are lines of symmetry:The belt along lines below are non lines of symmetry. Though they do stripe the figures in half, they dont create mirror-image halves.You can use a Mira (image reflector) or exactly the process of cutting and folding to find lines of symmetry.  im press the PDF  interpretation of the figures above, and compare the lines proposed using a Mira.In Problems A1 and A2, sketch the figures or  ingrain 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 vertical or horizontal.

For example, the arrow shown below has a line of symmetry, but the fact that it is not vertically or horizontally orientated means that students pwhitethorn not identify it.   Illustration 2 Students whitethorn think that a shape can whole develop one line of symmetry or may only identify some of the! lines that are present. For example, some students may be able to see just the vertical line of symmetry in the flower shape below (as in the first gear diagram), whereas others will see the three lines shown in the second diagram. In fact, there are are sise lines of symmetry, as seen in the third picture.   Illustration 3 Students may think that all lines which divide a shape into two equal halves are lines of symmetry.
