Here, each half is a perfect reflection of the other part. This occurs when the mirror line works as a line of symmetry that divides a shape into identical halves. So in a nutshell, the reflectional symmetry for symmetrical figures is also referred as a bilateral or mirror symmetry. The image, however, is a lateral inversion of the real figure. This means that the lengths and angles of the mirror image are identical to the lengths and angles of the real image. When a figure is reflected about the mirror line then the reflection image is congruent to the real image. Only alphabets A, H, I, M, O, T, U, V, W, X, and Y are identical reflections of the real image. When an alphabet is seen in the mirror we see its exactly inverted reflection. Now, let’s take the case of a figure or shape or an alphabet. The image formed in the mirror is a reflection of the object in the line of symmetry. This line of the fold is like the mirror line. When a paper is folded exactly in the middle, the line of the fold is the line of symmetry. So when we see an image of an object in the mirror, then the object is symmetrical with its mirror image. The mirror line here is the line of symmetry. This object and its reflection image show mirror symmetry. The left and right sides of an object appear inverted in the mirror. Now, what you see in the mirror is a reflection of yourself and is called the mirror image or reflection image.Īn object and its mirror image are perfectly identical to each other. When you see yourself in the mirror you can see an identical person of same size and shape and face in the mirror.
In fact, our day starts with looking in the mirror. Seeing yourself in the mirror is the most common thing that we do in a day.
