SYMMETRYNature is replete in symmetry. A butterfly’s wings are a good example. One half of the wings canbe folded on to the other half to match exactly. The fold then becomes the line of symmetry.1. Cut a pattern on apostcard. Push a pin inone comer and drawthe pattern. Rotate aquarter turn and drawagain. You will get abeautiful pattern showingrotational symmetry.2. Fold a paper inhalf. Cut shapes onits two edges. Openthe paper to see asymmetric pattern.Which is the line ofsymmetry?3. You can also cut symmetricshapes and patterns in leaves.Invent a lot of new shapes.4. Draw a shape and put amirror besides it so that theshape doubles itself.5. Search for compoundleaves that look as if they havebeen doubled up in a mirror.6. Stand the mirror on this masterfigure. Slide and turn the mirror tosee the patterns change. Now orientthe mirror in such a way so that youcan see the pattern, which matcheswith figure (7).7. Is your mirror on avertical line facing tothe right?8. Again place the minor onthe master pattern Fig (6) indifferent orientations to get allthese patterns.Mirror Puzzle9. Stand your mirror on this master pattern each time, in different orientations, to get the rest of thepatterns. You will be able to get most of them. But some of the patterns have been included totrick you. They are not simply hard, but impossible. Can you locate the impossible ones? If youhave enjoyed these mirror puzzles why not make some of your own.MasterPattern
