Which letters have reflection symmetry

Use thin rectangular coloured paper. Fold it several times and create some intricate patterns by cutting the paper in different patterns. There are plenty of lines of symmetry such decorative paper cut-outs are used for festive occasions. A kaleidoscope uses mirrors to produce images that have several lines of symmetry. Usually, two mirrors strips forming a V shape are used.

The angle between the mirrors determines the number of lines of symmetry. Make a kaleidoscope and try to learn more about the symmetric images produced. Kolams and Rangoli are popular in our country. Note the use of symmetry in them. Collect as many patterns as possible of these and prepare an album. Some will have line symmetry - that is, folding or mirror symmetry.

All of them have rotation turning symmetry. So you can spin them around and on the way around they match up with own starting position at least twice. Cite this Simulator:. The colorful design above has only vertical and horizontal lines of symmetry, but placing a mirror on it at another angle can create a beautiful new design. More intrepid experiments give other interesting results.

Note that some figures, like the star and the colorful blob at the top of the page, but not the letters N, Z, or S, have both reflective and rotational symmetry. A circle has infinitely many lines of symmetry: any diameter lies on a line of symmetry through the center of the circle.

Any rotation of any amount around the center of the circle also leaves the circle unchanged. Symmetry Topics: Mathematical Language. Mathematical Domain: Geometry. Mirror Play Well before children begin any formal study of symmetry, playing with mirrors — perhaps on Pattern Block designs that they build — develops experience and intuition that can serve both their geometric thinking and their artistic ideas. The same is true of the letter M. Letters like B and D have a horizontal line of symmetry: their top and bottom parts match.
