Fold it several times and create some intricate patterns by cutting the paper in different patterns. Symmetry has plenty of applications in real life, as in art, architecture, textiles designing, geometrical reasoning, Kolams, Rangoli, etc. The letters A, H, I, M, O, T, U, V, W, X and Y appear the same in their mirror image.Īll the other letters of the alphabet appear reversed in their mirror image. Letters like A, M and U appear the same in their mirror image. Letters written from right to left, appear written from left to right in their mirror image. The left and the right sides of an object appear inverted in a mirror.Here is an example that shows the refelection symmetry. there is a difference between the object and the image. However, in one aspect there is a change, i.e. the lengths and angles of the object and the corresponding lengths and angles of the image are the same. When an object is reflected, there is no change in the lengths and angles i.e. We then say that the image is the reflection of the object in the mirror line. The object and its image are symmetrical with reference to the mirror line. If the paper is folded, the mirror line becomes the line of symmetry. Line symmetry and mirror reflection are naturally related and linked to each other. A figure may have both horizontal and vertical lines of reflection.Īn object and its image are always at the same distance from the surface of a mirror, which is called the mirror line. A Reflectional Symmetry is a type of symmetry in which one half of the object is the mirror image of the other.
