FAQs on Important Questions for CBSE Class 6 Maths Chapter 13 - Symmetry
1. What is symmetry in Class 6 Maths?
Chapter 13 in the Class 6 Maths textbook explains to you what symmetry is. In simpler terms, symmetry can be explained this way. When you draw a line dividing a figure or an object into half, the two halves will be the same in their proportion. The two halves will be like a mirror image. When one half is placed on the other half, the first half will superimpose it. For example, when you fold a sheet of paper in half and then cut it, the two halves of the sheet will be symmetrical.
2. How many lines of symmetry does a figure have?
When a figure or an object is folded or cut into two halves, the line dividing or cutting the figure is called the axis of symmetry/line of symmetry. All regular and irregular figures can have at least one axis of symmetry. The lines of the axis vary depending upon the shape of the figure or object in question. For example, there is no line of symmetry in the letter F. No matter what axis of symmetry you draw, there will be no two equal halves. However, the letter A has one line of symmetry that when drawn vertically divides the letter in two equal halves.
3. How many lines of symmetry are there in a square, triangle and a circle?
The line of symmetry divides an object or figure in two similar, mirror-like images. A figure can have zero lines of symmetry such as a scalene triangle. Similarly, a regular pentagon could have five axes of symmetry. A square has four lines of symmetry - vertical, horizontal and two diagonals. The line of symmetry varies in a triangular shape - zero symmetrical line in a scalene triangle, one in an isosceles triangle and three lines in an equilateral triangle. A circle has infinite lines of symmetry.
4. What types of symmetry lines are explained in Class 6 Maths Chapter 13?
Three types of symmetrical lines are explained in Chapter 13 of the Class 6 Maths textbook. First is the vertical line of symmetry. This straight, vertical line divides the figure into two identical halves. The second is the horizontal line of symmetry. The line divides the figure horizontally into two halves. The last one is the diagonal line of symmetry. The diagonal line goes through the figure diagonally. If it divides the shapes, in identical halves, it is called a diagonal line of symmetry.
5. How should I study Chapter 13 of the Class 6 Maths textbook?
To prepare well for the Symmetry Chapter of Class 6, you should start with the basics. Understand what symmetry is and what the lines of symmetry are. Underline important points or make notes. Before you start practising your questions go through your notes or underlined points. Make the diagrams given in the textbook to understand the concept better. When you come across an object in your daily life, think about how it can be divided or what its lines of symmetry could be. Practice all the questions given and revise your notes regularly.
