Note: We can also solve this question by drawing a horizontal line passing through the center of the alphabet, as shown below. So, we can say that the letters, B, C, D, E, H, I, K, O and X are the letters which show the horizontal symmetry. If we consider the alphabets from A to Z then we need alphabets which are read as the same as the real alphabet even after the horizontal reflection. A reflection symmetry is a symmetrical figure in which one half of the figure is the mirror image of the other whereasrotational symmetry are those figures. We know that reflection of an image has a property that each point of reflection is at the same distance as in a real image. For that, we should know that mirror symmetry or reflectional symmetry is a symmetry which is obtained by drawing the mirror image. In this question, we have been asked to write the English alphabets which show horizontal reflectional symmetry. And when we consider the reflectional symmetry of the alphabets, then we can say that we will get the same shape of the alphabet after reflection. Retrieved 10 August 2023, from /index.Hint: To solve this question, we should know that reflectional symmetry is a symmetry which we find after drawing the reflection of an image horizontally. Symmetry has plenty of applications in everyday life as in art, architecture, textile technology, design creations, geometrical reasoning, Kolams, Rangoli etc.Ĭite this Simulator:.Alphabets written from right to left, appear written from left to right in their mirror image.When dealing with mirror reflection, we have to take into account the left right changes in orientation.The line symmetry is closely related to mirror reflection.So you can spin them around and on the way around they match up with own starting position at least twice. All of them have rotation (turning) symmetry. Some will have line symmetry - that is, folding or mirror symmetry. Collect as many patterns as possible of these and prepare an album. Kolams and Rangoli are popular in our country. Make a kaleidoscope and try to learn more about the symmetric images produced. The angle between the mirrors determines the number of lines of symmetry. Usually, two mirrors strips forming a V shape are used. There are plenty of lines of symmetry such decorative paper cut-outs are used for festive occasions.Ī kaleidoscope uses mirrors to produce images that have several lines of symmetry. 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. All the rest of the letters (F, G, J, K, L, N, P, Q, R, S and Z). The object and its image are symmetrical with reference to the mirror line. The capital letters H, I ,O and X all have both horizontal and vertical line symmetry. 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.
