Class 6 Maths - KERALA
Symmetry
In the Kerala SCERT Class 6 Mathematics chapter 'Symmetry', students explore how shapes and figures balance each other across a line. You will learn to identify lines of symmetry in everyday objects, geometric shapes like squares, rectangles, and triangles, and construct symmetrical patterns. Understanding symmetry helps in recognizing beauty and balance in nature and architecture. For board and school exams, this chapter is very scoring because questions are visual and straightforward. Examiners frequently test your ability to draw lines of symmetry in various polygons and complete symmetrical shapes using a grid.

Line of Symmetry
A line that divides a figure into two identical halves that fit exactly on top of each other when folded.
Symmetrical Figures
Shapes or objects that can be folded along a straight line so that both halves match completely.
Asymmetrical Figures
Figures that do not have any line of symmetry and cannot be divided into identical halves.
Multiple Lines of Symmetry
Some special shapes, like a square or a circle, can have more than one line of symmetry passing through them.

Board Exam Info
In the Kerala (SCERT) Class 6 Mathematics exams, this chapter usually carries around 4 to 6 marks. Common question types include drawing lines of symmetry for given geometrical shapes, identifying the number of lines of symmetry in letters of the English alphabet, and completing the other half of a symmetrical figure on a dot grid.
Frequently Asked Questions
How many lines of symmetry does a rectangle have?
A rectangle has 2 lines of symmetry: one horizontal and one vertical passing through the center.
Do all triangles have lines of symmetry?
No. An equilateral triangle has 3, an isosceles triangle has 1, but a scalene triangle has zero lines of symmetry.
Can a figure have more than one line of symmetry?
Yes, many geometric shapes like squares, rectangles, and regular polygons have multiple lines of symmetry.
