For example, an equilateral triangle, a square, alphabets like \(A,B,E,\) numbers like \(0,3,8\) etc., have line/lines of symmetry. Which shape has only one line of symmetry?Īns: A kite, alphabets like \(T,U,V,W,\) numbers like \(3,8\) etc., have only one line of symmetry.Īns: Many shapes have line symmetry. If you were to place a mirror along the line, the shape would remain unchanged. This would mean both halves of the object or shape match exactly if you were to fold the shape along the line of symmetry.
We can find the line/lines of symmetry by dividing the shape vertically, horizontally or both.Īns: A line of symmetry is a line that cuts a shape exactly in half. Frequently Asked Questions (FAQs)Īns: When you divide a figure into two halves, we say a figure has line/lines of symmetry. We also understood that many things, numbers, and alphabets have one, two, three or multiple lines of symmetry. In addition to that, we learned that particular objects, numbers, and alphabets possess vertical lines of symmetry and horizontal lines of symmetry. We also learned about the lines of symmetry. In this article, we learned the concept of symmetry and looked at many shapes and objects symmetrical in nature. The correct match will be as follows: Parallelogram ParallelogramĪns: Based on the shapes, we can draw the lines of symmetry. Match the following given shapes with their number of lines of symmetry. The infinite number of lines passes through the point symmetry about the centre \(O\) with all possible diameters. How many lines of symmetry does a circle have?Īns: A circle has infinite lines of symmetry. List the numbers from \(0\) to \(9\) that do not have even a single line of symmetry.Īns: The numbers from \(0\) to \(9\) are \(0,1,2,3,4,5,6,7,8\) and \(9.\) Out of these numbers, \(1,2,4,5,6,7\) and \(9\) have no or zero lines of symmetry. Symmetry is applicable in geometry as well. The axis of symmetry is a line that divides a shape into two halves, creating a mirror image of either side of the halves. \(ABCDEF\) is a regular hexagonĪ regular hexagon has \(6\) lines of symmetry. Line of Symmetry in a Regular Hexagon: A regular hexagon is defined as a hexagon that is both equilateral and equiangular. The measure of each angle of an equilateral triangle is \(.\)Ī regular pentagon has \(5\) lines of symmetry. Line of Symmetry in an Equilateral Triangle: All three sides of an equilateral triangle are equal. Let us discuss the line of symmetry of some of the regular polygons one by one in detail. The number of lines of symmetry in a regular polygon is equal to the number of sides a regular polygon has. Each regular polygon, like an equilateral triangle, square, rhombus, regular pentagon, regular hexagon, etc., is symmetrical. Therefore, all sides have the same length in a regular polygon, and all angles have equal measures. In contrast, the vertical line of symmetry divides the figure into left and right, which are mirror images of each other.Ī polygon is a closed shape made by \(3\) or more line segments. Thus, the horizontal line of symmetry divides the figure into the top and bottom that are mirror images of each other. In the first two alphabets, \(B\) and \(C,\) the line of symmetry is horizontal, and in the following two alphabets, \(T\) and \(H,\) the line of symmetry is vertical. Have a look at a few English alphabets given below. For instance, insects, flowers, animals, designs, architectures, notebooks, shapes and alphabets, etc., have symmetry.Ī shape can have a horizontal or vertical line of symmetry or both. Symmetry can be found anywhere in nature. Learn Exam Concepts on Embibe Types of Lines of Symmetry Horizontal and Vertical Lines of Symmetry In the above-given figures, the red coloured line divides each figure into two halves, and suppose we fold them along that line, and we will see that one half of each figure exactly coincides with the other half.Ī figure may have zero, one, two, three or infinite lines of symmetry. The line that divides a figure into two identical halves is called the line of symmetry. Learn 11th CBSE Exam Concepts Line of Symmetry Definition Thus, the two halves that Dhruv got after unfolding the sheet of paper are identical.
Well, when a figure is folded into two halves such that both the halves are identical, then we say that the figure is symmetrical. What can you say about the two halves Dhruv got in both cases?
