Class 4 Maths - HARYANA
Fun with Symmetry
The chapter 'Fun with Symmetry' in Class 4 Mathematics helps students discover balance and beauty in shapes around them. Children learn to identify symmetrical figures by folding paper and drawing lines of symmetry. They explore mirror halves where one side is the exact reflection of the other. This chapter is important for the Haryana Board (BSEH) exams because it builds strong visual and spatial reasoning skills. Students regularly face questions involving drawing lines of symmetry on letters, numbers, and geometric shapes like squares and rectangles, making it a scoring and foundational topic for their mathematical growth.

Symmetry
When a shape looks identical on both sides when folded or divided in half, it is called a symmetrical shape.
Line of Symmetry
The imaginary straight line that divides a figure into two exact mirror-image halves is known as the line of symmetry.
Mirror Halves
Two parts of a shape that match each other completely like an object and its reflection in a mirror.
Asymmetrical Shapes
Shapes that cannot be divided into two identical halves are called asymmetrical or non-symmetrical shapes.
Multiple Lines of Symmetry
Some special shapes, like squares and circles, can be divided symmetrically in more than one direction.

Board Exam Info
In the Haryana (BSEH) Class 4 Mathematics examination, this chapter usually carries around 4 to 6 marks. Common question types include drawing the line of symmetry for given figures, completing the other half of a symmetrical drawing, and identifying whether a given shape or alphabet letter is symmetrical or not.
Frequently Asked Questions
What is a line of symmetry?
A line of symmetry is a straight line that divides a shape into two identical halves that fit perfectly on top of each other.
Do all shapes have a line of symmetry?
No, some shapes are asymmetrical and do not have any line of symmetry because their halves do not match.
How many lines of symmetry does a rectangle have?
A rectangle has 2 lines of symmetry: one horizontal and one vertical.
