Class 6 Maths - MAHARASHTRA
Symmetry
The chapter 'Symmetry' in Class 6 Mathematics under the Maharashtra State Board (MSBSHSE) introduces students to the concept of balance and reflection in geometric shapes. Students learn to identify lines of symmetry in various 2D figures, including letters of the English alphabet, regular polygons, and everyday objects. They will explore both line symmetry and mirror reflection, understanding how an object can be divided into identical halves. This chapter builds a strong visual and spatial foundation for geometry, frequently appearing in board exams through diagram-based identification questions, drawing lines of symmetry, and completing symmetrical figures.

Line of Symmetry
An imaginary line that divides a figure into two identical, overlapping halves when folded along the line.
Symmetrical Figures
Shapes or objects that look exactly the same on both sides of a dividing line, possessing one or more lines of symmetry.
Asymmetrical Figures
Shapes or objects that do not have any line of symmetry and cannot be divided into identical halves.
Mirror Reflection
The property where an object and its reflection in a mirror are symmetrical with respect to the mirror line.
Multiple Lines of Symmetry
Some special geometric shapes, like a square or an equilateral triangle, can have more than one line of symmetry.

Board Exam Info
In the Maharashtra (MSBSHSE) Class 6 Mathematics exams, this chapter typically carries around 4 to 6 marks. Common question types include drawing lines of symmetry for given figures, identifying whether given shapes are symmetrical or asymmetrical, completing symmetric shapes using a dotted line of symmetry, and multiple-choice questions about the number of symmetry lines in standard geometric shapes.
Frequently Asked Questions
What is the difference between a symmetrical and an asymmetrical figure?
A symmetrical figure can be folded along a line so that both halves match perfectly. An asymmetrical figure cannot be divided into identical halves.
How many lines of symmetry does a circle have?
A circle has an infinite number of lines of symmetry because any line passing through its center divides it into two identical halves.
Do all letters of the English alphabet have a line of symmetry?
No, only some letters like A, M, T, and V have vertical or horizontal lines of symmetry, while letters like F, G, and J have no line of symmetry.
