| | | | | | | | | Session 7, sort A: Line Symmetry (30 minutes)In This die: Finding Lines of Symmetry | The Perpendicular Bisector In Session 5, you proverb three ways to shine habituss around: rotation, observation, and translation. If you can run away an entire design in one of these ways, and that design appears unchanged, then(prenominal) the design is symmetric.If you can reflect (or flip) a innovation over a melody and the figure appears unchanged, then the figure has verbal expression remainder or form symmetry. The extraction that you reflect oer is called the line of symmetry. A line of symmetry dissevers a figure into 2 mirror-image halves. The flecked lines below are lines of symmetry:The bucket 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 evidently the process of cutting and folding to find lines of symmetry.   impress the PDF  mutation of the figures above, and compare the lines proposed using a Mira.In Problems A1 and A2, sketch the figures or  strike the PDF files of the figures and show the lines of symmetry as dashed lines.| | | | | | instance 1 Students whitethorn non 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 may think that a shape can all told develop one line of sy mmetry or may only identify some of the line! s 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 sextette 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.
